Masechet Chullin is sponsored by Judi Felber in honor of the Hadran Community. “During my first cycle of Daf Yomi, just as we began Masechet Chullin, my son was injured while serving in the IDF. Throughout those two and a half months of difficulty and uncertainty, my fellow learners never left my side. With profound gratitude to the community that held me, encouraged me, and ensured I could keep up with the Daf during those trying times.”
Today’s daf is sponsored by Roslyn Jaffe in loving memory of her father, Mickey Muhlrad, Moshe Yaakov ben Dovid on his 13th yahrzeit. “He epitomized Chesed, never spoke Loshen Hara and, above all, valued a Torah education. Having to flee from Europe before his bar-mitzvah, my father’s education was cut short, but he ensured that all his descendants would have a proper Jewish education. Little did he know that I’d be learning Daf Yomi, but I’m sure he’s shepping nachas!”

The Gemara answers: Forbidden fat is different from the sciatic nerve, because its flavor permeates throughout the animal, unlike that of the sciatic nerve.
וּבְחֵלֶב אָסוּר? וְהָאָמַר רַבָּה בַּר בַּר חָנָה: עוֹבָדָא הֲוָה קַמֵּיהּ דְּרַבִּי יוֹחָנָן בִּכְנִישְׁתָּא דְמָעוֹן, בִּגְדִי שֶׁצְּלָאוֹ בְּחֶלְבּוֹ, וַאֲתוֹ וְשַׁיְילוּהּ לְרַבִּי יוֹחָנָן, וְאָמַר: קוֹלֵף וְאוֹכֵל עַד שֶׁמַּגִּיעַ לְחֶלְבּוֹ! הָהוּא כָּחוּשׁ הֲוָה.
The Gemara challenges Rav Huna’s statement: And in the case of a kid roasted with its forbidden fat, is the meat forbidden? But didn’t Rabba bar bar Ḥana say: There was an incident that came before Rabbi Yoḥanan in the synagogue of the town of Maon, where a young goat was roasted with its fat, and the people came and asked Rabbi Yoḥanan about the status of the meat, and he said: Peel away the meat and eat it until you reach the forbidden fat? This indicates that the flavor of the fat does not permeate the entire animal in which it is roasted. The Gemara answers: That kid was lean and had so little fat that its flavor did not permeate throughout the animal.
רַב הוּנָא בַּר יְהוּדָה אָמַר: כּוּלְיָא בְּחֶלְבָּהּ הֲוָה, וְשַׁרְיַאּ. רָבִין בַּר רַב אַדָּא אָמַר: כִּילְכִּית בְּאִילְפָּס הֲוָה, וַאֲתוֹ שַׁיְילוּהּ לְרַבִּי יוֹחָנָן, וַאֲמַר לְהוּ: לִיטְעֲמֵיהּ קַפִּילָא אֲרַמָּאָה.
Rav Huna bar Yehuda said: That was a case of a kidney of a young goat roasted with its forbidden fat, and Rabbi Yoḥanan permitted it to be eaten because there is a membrane that separates the fat from the kidney and prevents the fat from penetrating the kidney. Ravin bar Rav Adda said: That was a case of a small, non-kosher fish known as kilkhit, which fell into a stewpot [ilpas], and they came to ask Rabbi Yoḥanan about its status. And he said to them: Let a gentile cook [kapeila] taste it in order to determine whether the flavor of the non-kosher fish has permeated the entire mixture.
אָמַר רָבָא: מֵרֵישׁ הֲוָה קָא קַשְׁיָא לִי הָא דְּתַנְיָא: קְדֵרָה שֶׁבִּשֵּׁל בָּהּ בָּשָׂר – לֹא יְבַשֵּׁל בָּהּ חָלָב, וְאִם בִּשֵּׁל – בְּנוֹתֵן טַעַם; תְּרוּמָה – לֹא יְבַשֵּׁל בָּהּ חוּלִּין, וְאִם בִּשֵּׁל – בְּנוֹתֵן טַעַם.
Rava said: Initially that which is taught in the following baraita posed a difficulty for me: With regard to a pot in which one cooked meat, one may not cook milk in it; and if he did cook milk in it, the meat absorbed by the pot renders the milk forbidden if it imparts flavor to the milk. Similarly, if one cooked teruma in a pot, one may not cook non-sacred food in it; and if one did cook non-sacred food in it, the absorbed teruma renders the food in the pot sacred if it imparts flavor to it.
בִּשְׁלָמָא תְּרוּמָה, טָעֵים לַהּ כֹּהֵן, אֶלָּא בָּשָׂר בְּחָלָב – מַאן טָעֵים לֵיהּ? הַשְׁתָּא דְּאָמַר רַבִּי יוֹחָנָן: סָמְכִינַן אַקַּפִּילָא אֲרַמָּאָה, הָכָא נָמֵי סָמְכִינַן אַקַּפִּילָא אֲרַמָּאָה.
Rava explains: Granted, in the case of a pot used for teruma, a priest, who is permitted to partake of teruma, can taste the non-sacred food subsequently cooked in the pot in order to determine whether the teruma imparted flavor to the non-sacred food. But in a case where it is not known whether meat imparted flavor into milk, who can taste it? If the meat did impart flavor to the milk, it would be forbidden for any Jew to consume the milk. But now that Rabbi Yoḥanan said: We rely on a gentile cook in the case of the kilkhit, here also we rely on a gentile cook to taste it and say whether the meat has imparted flavor to the milk.
דְּאָמַר רָבָא: אֲמוּר רַבָּנַן בְּטַעְמָא, וַאֲמוּר רַבָּנַן בְּקַפִּילָא,
The Gemara summarizes the guidelines that determine when an item cooked with another item affects the status of the mixture. Rava said: The Sages said that there are cases where one relies on a Jew tasting the food, and the Sages said that there are some cases where one relies on a gentile cook to taste the food,
וַאֲמוּר רַבָּנַן בְּשִׁשִּׁים. הִלְכָּךְ, מִין בְּשֶׁאֵינוֹ מִינוֹ דְּהֶיתֵּרָא – בְּטַעְמָא, דְּאִיסּוּרָא – בְּקַפִּילָא.
and the Sages said that there are cases where the mixture is permitted if there is sixty times as much permitted food as forbidden food. Therefore, in a case where the mixture is a type of food mixed with food not of its own type, so that there is a difference in taste between the two components, when there are Jews for whom the mixture is permitted, one relies on a Jew tasting the mixture. This is the halakha when teruma is cooked with non-sacred food. When the mixture is potentially forbidden, e.g., in the case of meat cooked with milk, one relies on a gentile cook to taste it.
וּמִין בְּמִינוֹ, דְּלֵיכָּא לְמֵיקַם אַטַּעְמָא, אִי נָמֵי מִין בְּשֶׁאֵינוֹ מִינוֹ דְּאִיסּוּרָא, דְּלֵיכָּא קַפִּילָא – בְּשִׁשִּׁים.
And if the mixture is composed of a type of food mixed with food of its own type, where one cannot ascertain whether the forbidden component has imparted flavor; or if it is composed of a type of food mixed with food not of its own type when the mixture may be forbidden and it is a case where there is no gentile cook available to taste it, the mixture is permitted if there is sixty times as much permitted food as forbidden food.
הָנְהוּ אַטְמָהָתָא דְּאִימְּלִיחוּ בֵּי רֵישׁ גָּלוּתָא בְּגִידָא נַשְׁיָא, רָבִינָא אָסַר, רַב אַחָא בַּר רַב אָשֵׁי שָׁרֵי. אֲתוֹ שַׁיְילוּהּ לְמָר בַּר רַב אָשֵׁי, אֲמַר לְהוּ: אַבָּא שָׁרֵי.
§ The Gemara (96b) cited Shmuel’s opinion with regard to the thigh of an animal that was roasted or cooked with the sciatic nerve still inside. The Gemara relates the following incident: There were those animal thighs that were salted in the home of the Exilarch with the sciatic nerve still inside; Ravina ruled that they were forbidden, whereas Rav Aḥa bar Rav Ashi ruled that they were permitted. They came and asked Mar bar Rav Ashi to render a decision. He said to them: My father permitted the meat in such circumstances.
אֲמַר לֵיהּ רַב אַחָא בַּר רַב לְרָבִינָא: מַאי דַּעְתָּיךְ – דְּאָמַר שְׁמוּאֵל: מָלִיחַ הֲרֵי הוּא כְּרוֹתֵחַ, כָּבוּשׁ הֲרֵי הוּא כִּמְבוּשָּׁל.
Rav Aḥa bar Rav said to Ravina: What is your reasoning in prohibiting the meat? Is it because of what Shmuel said: A salted food item is considered like a boiling hot food item, and a food item marinated in vinegar, brine, or the like is considered like a cooked food item? Perhaps based on this statement of Shmuel you consider the salted thighs as though they have been cooked with their sciatic nerves, in which case they are forbidden.
וְהָאָמַר שְׁמוּאֵל: לֹא שָׁנוּ אֶלָּא שֶׁנִּתְבַּשֵּׁל בָּהּ, אֲבָל נִצְלָה בָּהּ – קוֹלֵף וְאוֹכֵל עַד שֶׁמַּגִּיעַ לַגִּיד.
But didn’t Shmuel also say (96b): They taught that the thigh is entirely forbidden only when it was cooked with the sciatic nerve inside it. But if the sciatic nerve was roasted inside the thigh, one may peel away the meat and eat it until he reaches the sciatic nerve, and then he removes the nerve.
וְכִי תֵּימָא, מַאי כְּרוֹתֵחַ דְּקָאָמַר? כְּרוֹתֵחַ דִּמְבוּשָּׁל! וְהָא מִדְּקָאָמַר כָּבוּשׁ הֲרֵי הוּא כִּמְבוּשָּׁל, מִכְּלָל דְּרוֹתֵחַ דְּצָלִי קָאָמַר. קַשְׁיָא.
And if you would say: What is the meaning of the phrase: Like a boiling hot food item, that Shmuel said? It is like boiling hot food that was cooked rather than hot food that was roasted, and therefore if the thigh was salted with its sciatic nerve the entire thigh becomes forbidden. This is not a convincing claim, because from the fact that Shmuel said: A food item marinated in vinegar, brine, or the like is considered like a cooked food item, it may be understood by inference that when he said that salted food is like boiling hot food he was saying that it is like boiling hot food that is roasted. The Gemara concludes: This poses a difficulty to the opinion of Ravina.
אָמַר רַבִּי חֲנִינָא: כְּשֶׁהֵן מְשַׁעֲרִין, מְשַׁעֲרִין בְּרוֹטֶב וּבַקֵּיפֶה וּבַחֲתִיכוֹת וּבִקְדֵרָה. אִיכָּא דְּאָמְרִי: בִּקְדֵרָה עַצְמָהּ, וְאִיכָּא דְּאָמְרִי: בְּמַאי דְּבָלְעָה קְדֵרָה.
§ The Gemara elaborates on the statement that if permitted and forbidden foods are cooked together and there is sixty times as much permitted food as forbidden food, the mixture is permitted. Rabbi Ḥanina says: When they assess whether or not there is sixty times as much permitted food, they assess the volume of the broth, the deposits [kifa], the pieces of permitted food cooked in the pot, and the pot itself. The Gemara explains this last point: There are those who say this means that one includes the volume of the material of the pot itself, and there are those who say it means that one includes the volume of that which the pot has absorbed from the permitted food. When meat cooks its volume decreases, and some of the meat that constitutes that discrepancy is absorbed into the sides of the pot.
אָמַר רַבִּי אֲבָהוּ אָמַר רַבִּי יוֹחָנָן: כׇּל אִיסּוּרִין שֶׁבַּתּוֹרָה (מְשַׁעֲרִינַן) [מְשַׁעֲרִין אוֹתָן] כְּאִילּוּ הֵן בָּצָל וְקַפְלוֹט.
The Gemara continues its discussion of nullification. Rabbi Abbahu says that Rabbi Yoḥanan says: With regard to all forbidden foods that are prohibited in the Torah, if they are cooked with permitted food and one cannot tell whether they have imparted flavor to the permitted food, we assess the mixture as though the forbidden food were onion or leek [kaflot]. If that amount of onions or leeks would impart flavor to the permitted food, one must assume that the mixture is forbidden.
אֲמַר לֵיהּ רַבִּי אַבָּא לְאַבָּיֵי: וּלְשַׁעֲרִינְהוּ בְּפִלְפְּלִין וְתַבְלִין, דַּאֲפִילּוּ בְּאֶלֶף לֹא בְּטֵלִין! אֲמַר לֵיהּ: שִׁיעֲרוּ חֲכָמִים דְּאֵין נוֹתֵן טַעַם בְּאִיסּוּרִין יוֹתֵר מִבָּצָל וְקַפְלוֹט.
Rabbi Abba said to Abaye: But let one assess the mixture as though the forbidden food were pepper or other spices, which are even more pungent, in which case they would not be nullified even if they were mixed with a thousand times as much permitted food. Abaye said to him: The Sages ascertained that with regard to forbidden foods, there is nothing that imparts more flavor to a mixture than onion and leek.
אָמַר רַב נַחְמָן: גִּיד בְּשִׁשִּׁים, וְאֵין גִּיד מִן הַמִּנְיָן; כְּחָל בְּשִׁשִּׁים, וּכְחָל מִן הַמִּנְיָן; בֵּיצָה בְּשִׁשִּׁים, וְאֵין בֵּיצָה מִן הַמִּנְיָן.
§ The Gemara continues to discuss the nullification of forbidden foods. Rav Naḥman says: A sciatic nerve that was cooked with kosher food is nullified if the mixture contains permitted food that is sixty times the nerve’s volume, and the sciatic nerve itself is not counted in that number, because it cannot nullify itself. If an udder, which is meat but also contains milk, is cooked with other meat, the milk is nullified if the meat is sixty times its volume, and the udder itself is counted with the rest of the meat. If the egg of a non-kosher bird is cooked with kosher food, it is nullified if the permitted food is sixty times its volume, and the egg itself is not counted in that number, as it cannot nullify itself.
אָמַר רַבִּי יִצְחָק בְּרֵיהּ דְּרַב מְשַׁרְשְׁיָא: וּכְחָל עַצְמוֹ אָסוּר, וְאִי נָפַל לִקְדֵרָה אַחֶרֶת – אוֹסֵר.
Rabbi Yitzḥak, son of Rav Mesharshiyya, says: In the case of an udder cooked with meat, even if the meat is sixty times the volume of the milk, so that the meat is permitted, the udder itself is forbidden, because the meat imparts flavor to the milk contained within the udder, which then renders the udder forbidden. And if the udder subsequently falls into another pot, it also renders the contents of that pot forbidden unless they are sixty times the volume of the udder.
אָמַר רַב אָשֵׁי: כִּי הֲוֵינַן בֵּי רַב כָּהֲנָא, אִיבַּעְיָא לַן: כִּי מְשַׁעֲרִינַן בְּדִידֵיהּ מְשַׁעֲרִינַן, אוֹ בְּמַאי דִּנְפַק מִינֵּיהּ מְשַׁעֲרִינַן?
Rav Ashi said: When we were in the study hall of Rav Kahana, a dilemma was raised before us: When we assess whether the contents of the pot are sufficient to nullify the udder, do we assess whether the pot contains sixty times as much permitted food as the entire volume of the meat of the udder itself, or do we assess only that milk which came out from the udder, since the udder itself has been removed from the mixture?
פְּשִׁיטָא דִּבְדִידֵיהּ מְשַׁעֲרִינַן, דְּאִי בְּמָה דִּנְפַק מִינֵּיהּ – מְנָא יָדְעִינַן? אֶלָּא מֵעַתָּה, נָפַל לִקְדֵרָה אַחֶרֶת – לֹא יֶאֱסֹר?
The Gemara responds: It is obvious that we assess the entire volume of the meat of the udder itself, as if we were to attempt to assess only that which came out of it, how would we know how much came out? The Gemara objects: If that is so, then if the udder falls into another pot, it should not render the food in that second pot forbidden, because it has been assumed that all the milk in the udder has been released into the first pot.
כֵּיוָן דְּאָמַר רַב יִצְחָק בְּרֵיהּ דְּרַב מְשַׁרְשְׁיָא: וּכְחָל עַצְמוֹ אָסוּר, שַׁוְּיוּהּ רַבָּנַן כַּחֲתִיכָה דִּנְבֵלָה.
The Gemara explains: Since Rav Yitzḥak, son of Rav Mesharshiyya, says that even if there is sixty times as much meat in the pot as there is milk in the udder, the udder itself is forbidden, clearly the Sages equated the udder with a piece of non-kosher meat. Consequently, the reason the udder renders the contents of the second pot forbidden is that the udder is intrinsically forbidden, not because of the milk that is released into the pot while it is being cooked.
בֵּיצָה בְּשִׁשִּׁים, וְאֵין בֵּיצָה מִן הַמִּנְיָן. אֲמַר לֵיהּ רַב אִידִי בַּר אָבִין לְאַבָּיֵי: לְמֵימְרָא דְּיָהֲבָה טַעְמָא? וְהָא אָמְרִי אִינָשֵׁי: כִּי מַיָּא דְּבֵיעֵי בְּעָלְמָא!
§ The Gemara addresses Rav Naḥman’s statement that if the egg of a non-kosher bird is cooked with kosher food, it is nullified if the permitted food is sixty times its volume, and the egg itself is not counted in that number, as it cannot nullify itself. Rav Idi bar Avin said to Abaye: Is this to say that the forbidden egg imparts flavor to the food with which it is cooked? But isn’t it true that when people want to indicate that food is tasteless, they say: This is like mere egg-water? This indicates that an egg does not impart flavor.

The Hadran Women’s Tapestry
Meet the diverse women learning Gemara at Hadran and hear their stories.
As Jewish educator and as a woman, I’m mindful that Talmud has been kept from women for many centuries. Now that we are privileged to learn, and learning is so accessible, it’s my intent to complete Daf Yomi. I am so excited to keep learning with my Hadran community.
Denver, United States
A few years back, after reading Ilana Kurshan’s book, “If All The Seas Were Ink,” I began pondering the crazy, outlandish idea of beginning the Daf Yomi cycle. Beginning in December, 2019, a month before the previous cycle ended, I “auditioned” 30 different podcasts in 30 days, and ultimately chose to take the plunge with Hadran and Rabbanit Michelle. Such joy!
HUNTINGTON, United States
I began my journey two years ago at the beginning of this cycle of the daf yomi. It has been an incredible, challenging experience and has given me a new perspective of Torah Sh’baal Peh and the role it plays in our lives
Efrat, Israel
I began daf yomi in January 2020 with Brachot. I had made aliya 6 months before, and one of my post-aliya goals was to complete a full cycle. As a life-long Tanach teacher, I wanted to swim from one side of the Yam shel Torah to the other. Daf yomi was also my sanity through COVID. It was the way to marking the progression of time, and feel that I could grow and accomplish while time stopped.
Givat Zev, Israel
After being so inspired by the siyum shas two years ago, I began tentatively learning daf yomi, like Rabbanut Michelle kept saying – taking one daf at a time. I’m still taking it one daf at a time, one masechet at a time, but I’m loving it and am still so inspired by Rabbanit Michelle and the Hadran community, and yes – I am proud to be finishing Seder Mo’ed.
Bet Shemesh, Israel
In my Shana bet at Migdal Oz I attended the Hadran siyum hash”as. Witnessing so many women so passionate about their Torah learning and connection to God, I knew I had to begin with the coming cycle. My wedding (June 24) was two weeks before the siyum of mesechet yoma so I went a little ahead and was able to make a speech and siyum at my kiseh kallah on my wedding day!
Givat Shmuel, Israel
After reading the book, “ If All The Seas Were Ink “ by Ileana Kurshan I started studying Talmud. I searched and studied with several teachers until I found Michelle Farber. I have been studying with her for two years. I look forward every day to learn from her.
Virginia, United States
I started learning with rabbis. I needed to know more than the stories. My first teacher to show me “the way of the Talmud” as well as the stories was Samara Schwartz.
Michelle Farber started the new cycle 2 yrs ago and I jumped on for the ride.
I do not look back.

Richmond, CA, United States
I decided to give daf yomi a try when I heard about the siyum hashas in 2020. Once the pandemic hit, the daily commitment gave my days some much-needed structure. There have been times when I’ve felt like quitting- especially when encountering very technical details in the text. But then I tell myself, “Look how much you’ve done. You can’t stop now!” So I keep going & my Koren bookshelf grows…
Huntington, United States
I started learning Daf Yomi inspired by תָּפַסְתָּ מְרוּבֶּה לֹא תָּפַסְתָּ, תָּפַסְתָּ מוּעָט תָּפַסְתָּ. I thought I’d start the first page, and then see. I was swept up into the enthusiasm of the Hadran Siyum, and from there the momentum kept building. Rabbanit Michelle’s shiur gives me an anchor, a connection to an incredible virtual community, and an energy to face whatever the day brings.
בית שמש, Israel
After all the hype on the 2020 siyum I became inspired by a friend to begin learning as the new cycle began.with no background in studying Talmud it was a bit daunting in the beginning. my husband began at the same time so we decided to study on shabbat together. The reaction from my 3 daughters has been fantastic. They are very proud. It’s been a great challenge for my brain which is so healthy!
Modi’in, Israel
Hearing and reading about the siyumim at the completion of the 13 th cycle Daf Yomi asked our shul rabbi about starting the Daf – he directed me to another shiur in town he thought would allow a woman to join, and so I did! Love seeing the sources for the Divrei Torah I’ve been hearing for the past decades of living an observant life and raising 5 children .
Pittsburgh, Pennsylvania, United States
I started learning at the start of this cycle, and quickly fell in love. It has become such an important part of my day, enriching every part of my life.

I started at the beginning of this cycle. No 1 reason, but here’s 5.
In 2019 I read about the upcoming siyum hashas.
There was a sermon at shul about how anyone can learn Talmud.
Talmud references come up when I am studying. I wanted to know more.
Yentl was on telly. Not a great movie but it’s about studying Talmud.

Cambridge, United Kingdom
I began my Daf Yomi journey on January 5, 2020. I had never learned Talmud before. Initially it struck me as a bunch of inane and arcane details with mind bending logic. I am now smitten. Rabbanit Farber brings the page to life and I am eager to learn with her every day!
Highland Park, United States
Years ago, I attended the local Siyum HaShas with my high school class. It was inspiring! Through that cycle and the next one, I studied masekhtot on my own and then did “daf yomi practice.” The amazing Hadran Siyum HaShas event firmed my resolve to “really do” Daf Yomi this time. It has become a family goal. We’ve supported each other through challenges, and now we’re at the Siyum of Seder Moed!
Jerusalem, Israel
After being so inspired by the siyum shas two years ago, I began tentatively learning daf yomi, like Rabbanut Michelle kept saying – taking one daf at a time. I’m still taking it one daf at a time, one masechet at a time, but I’m loving it and am still so inspired by Rabbanit Michelle and the Hadran community, and yes – I am proud to be finishing Seder Mo’ed.
Bet Shemesh, Israel
Inspired by Hadran’s first Siyum ha Shas L’Nashim two years ago, I began daf yomi right after for the next cycle. As to this extraordinary journey together with Hadran..as TS Eliot wrote “We must not cease from exploration and the end of all our exploring will be to arrive where we began and to know the place for the first time.
Jerusalem, Israel
I’ve been wanting to do Daf Yomi for years, but always wanted to start at the beginning and not in the middle of things. When the opportunity came in 2020, I decided: “this is now the time!” I’ve been posting my journey daily on social media, tracking my progress (#DafYomi); now it’s fully integrated into my daily routines. I’ve also inspired my partner to join, too!

The Gemara answers: Forbidden fat is different from the sciatic nerve, because its flavor permeates throughout the animal, unlike that of the sciatic nerve.

Ravin bar Rav Adda said: That was a case of a small, non-kosher fish known as kilkhit, which fell into a stewpot [ilpas], and they came to ask Rabbi Yoḥanan about its status. And he said to them: Let a gentile cook [kapeila] taste it in order to determine whether the flavor of the non-kosher fish has permeated the entire mixture.

Rava explains: Granted, in the case of a pot used for teruma, a priest, who is permitted to partake of teruma, can taste the non-sacred food subsequently cooked in the pot in order to determine whether the teruma imparted flavor to the non-sacred food. But in a case where it is not known whether meat imparted flavor into milk, who can taste it? If the meat did impart flavor to the milk, it would be forbidden for any Jew to consume the milk. But now that Rabbi Yoḥanan said: We rely on a gentile cook in the case of the kilkhit, here also we rely on a gentile cook to taste it and say whether the meat has imparted flavor to the milk.
דְּאָמַר רָבָא: אֲמוּר רַבָּנַן בְּטַעְמָא, וַאֲמוּר רַבָּנַן בְּקַפִּילָא,
The Gemara summarizes the guidelines that determine when an item cooked with another item affects the status of the mixture. Rava said: The Sages said that there are cases where one relies on a Jew tasting the food, and the Sages said that there are some cases where one relies on a gentile cook to taste the food,
וַאֲמוּר רַבָּנַן בְּשִׁשִּׁים. הִלְכָּךְ, מִין בְּשֶׁאֵינוֹ מִינוֹ דְּהֶיתֵּרָא – בְּטַעְמָא, דְּאִיסּוּרָא – בְּקַפִּילָא.
and the Sages said that there are cases where the mixture is permitted if there is sixty times as much permitted food as forbidden food. Therefore, in a case where the mixture is a type of food mixed with food not of its own type, so that there is a difference in taste between the two components, when there are Jews for whom the mixture is permitted, one relies on a Jew tasting the mixture. This is the halakha when teruma is cooked with non-sacred food. When the mixture is potentially forbidden, e.g., in the case of meat cooked with milk, one relies on a gentile cook to taste it.
וּמִין בְּמִינוֹ, דְּלֵיכָּא לְמֵיקַם אַטַּעְמָא, אִי נָמֵי מִין בְּשֶׁאֵינוֹ מִינוֹ דְּאִיסּוּרָא, דְּלֵיכָּא קַפִּילָא – בְּשִׁשִּׁים.
And if the mixture is composed of a type of food mixed with food of its own type, where one cannot ascertain whether the forbidden component has imparted flavor; or if it is composed of a type of food mixed with food not of its own type when the mixture may be forbidden and it is a case where there is no gentile cook available to taste it, the mixture is permitted if there is sixty times as much permitted food as forbidden food.
הָנְהוּ אַטְמָהָתָא דְּאִימְּלִיחוּ בֵּי רֵישׁ גָּלוּתָא בְּגִידָא נַשְׁיָא, רָבִינָא אָסַר, רַב אַחָא בַּר רַב אָשֵׁי שָׁרֵי. אֲתוֹ שַׁיְילוּהּ לְמָר בַּר רַב אָשֵׁי, אֲמַר לְהוּ: אַבָּא שָׁרֵי.
§ The Gemara (96b) cited Shmuel’s opinion with regard to the thigh of an animal that was roasted or cooked with the sciatic nerve still inside. The Gemara relates the following incident: There were those animal thighs that were salted in the home of the Exilarch with the sciatic nerve still inside; Ravina ruled that they were forbidden, whereas Rav Aḥa bar Rav Ashi ruled that they were permitted. They came and asked Mar bar Rav Ashi to render a decision. He said to them: My father permitted the meat in such circumstances.
אֲמַר לֵיהּ רַב אַחָא בַּר רַב לְרָבִינָא: מַאי דַּעְתָּיךְ – דְּאָמַר שְׁמוּאֵל: מָלִיחַ הֲרֵי הוּא כְּרוֹתֵחַ, כָּבוּשׁ הֲרֵי הוּא כִּמְבוּשָּׁל.
Rav Aḥa bar Rav said to Ravina: What is your reasoning in prohibiting the meat? Is it because of what Shmuel said: A salted food item is considered like a boiling hot food item, and a food item marinated in vinegar, brine, or the like is considered like a cooked food item? Perhaps based on this statement of Shmuel you consider the salted thighs as though they have been cooked with their sciatic nerves, in which case they are forbidden.
וְהָאָמַר שְׁמוּאֵל: לֹא שָׁנוּ אֶלָּא שֶׁנִּתְבַּשֵּׁל בָּהּ, אֲבָל נִצְלָה בָּהּ – קוֹלֵף וְאוֹכֵל עַד שֶׁמַּגִּיעַ לַגִּיד.
But didn’t Shmuel also say (96b): They taught that the thigh is entirely forbidden only when it was cooked with the sciatic nerve inside it. But if the sciatic nerve was roasted inside the thigh, one may peel away the meat and eat it until he reaches the sciatic nerve, and then he removes the nerve.
וְכִי תֵּימָא, מַאי כְּרוֹתֵחַ דְּקָאָמַר? כְּרוֹתֵחַ דִּמְבוּשָּׁל! וְהָא מִדְּקָאָמַר כָּבוּשׁ הֲרֵי הוּא כִּמְבוּשָּׁל, מִכְּלָל דְּרוֹתֵחַ דְּצָלִי קָאָמַר. קַשְׁיָא.
And if you would say: What is the meaning of the phrase: Like a boiling hot food item, that Shmuel said? It is like boiling hot food that was cooked rather than hot food that was roasted, and therefore if the thigh was salted with its sciatic nerve the entire thigh becomes forbidden. This is not a convincing claim, because from the fact that Shmuel said: A food item marinated in vinegar, brine, or the like is considered like a cooked food item, it may be understood by inference that when he said that salted food is like boiling hot food he was saying that it is like boiling hot food that is roasted. The Gemara concludes: This poses a difficulty to the opinion of Ravina.
אָמַר רַבִּי חֲנִינָא: כְּשֶׁהֵן מְשַׁעֲרִין, מְשַׁעֲרִין בְּרוֹטֶב וּבַקֵּיפֶה וּבַחֲתִיכוֹת וּבִקְדֵרָה. אִיכָּא דְּאָמְרִי: בִּקְדֵרָה עַצְמָהּ, וְאִיכָּא דְּאָמְרִי: בְּמַאי דְּבָלְעָה קְדֵרָה.
§ The Gemara elaborates on the statement that if permitted and forbidden foods are cooked together and there is sixty times as much permitted food as forbidden food, the mixture is permitted. Rabbi Ḥanina says: When they assess whether or not there is sixty times as much permitted food, they assess the volume of the broth, the deposits [kifa], the pieces of permitted food cooked in the pot, and the pot itself. The Gemara explains this last point: There are those who say this means that one includes the volume of the material of the pot itself, and there are those who say it means that one includes the volume of that which the pot has absorbed from the permitted food. When meat cooks its volume decreases, and some of the meat that constitutes that discrepancy is absorbed into the sides of the pot.
אָמַר רַבִּי אֲבָהוּ אָמַר רַבִּי יוֹחָנָן: כׇּל אִיסּוּרִין שֶׁבַּתּוֹרָה (מְשַׁעֲרִינַן) [מְשַׁעֲרִין אוֹתָן] כְּאִילּוּ הֵן בָּצָל וְקַפְלוֹט.
The Gemara continues its discussion of nullification. Rabbi Abbahu says that Rabbi Yoḥanan says: With regard to all forbidden foods that are prohibited in the Torah, if they are cooked with permitted food and one cannot tell whether they have imparted flavor to the permitted food, we assess the mixture as though the forbidden food were onion or leek [kaflot]. If that amount of onions or leeks would impart flavor to the permitted food, one must assume that the mixture is forbidden.
אֲמַר לֵיהּ רַבִּי אַבָּא לְאַבָּיֵי: וּלְשַׁעֲרִינְהוּ בְּפִלְפְּלִין וְתַבְלִין, דַּאֲפִילּוּ בְּאֶלֶף לֹא בְּטֵלִין! אֲמַר לֵיהּ: שִׁיעֲרוּ חֲכָמִים דְּאֵין נוֹתֵן טַעַם בְּאִיסּוּרִין יוֹתֵר מִבָּצָל וְקַפְלוֹט.
Rabbi Abba said to Abaye: But let one assess the mixture as though the forbidden food were pepper or other spices, which are even more pungent, in which case they would not be nullified even if they were mixed with a thousand times as much permitted food. Abaye said to him: The Sages ascertained that with regard to forbidden foods, there is nothing that imparts more flavor to a mixture than onion and leek.
אָמַר רַב נַחְמָן: גִּיד בְּשִׁשִּׁים, וְאֵין גִּיד מִן הַמִּנְיָן; כְּחָל בְּשִׁשִּׁים, וּכְחָל מִן הַמִּנְיָן; בֵּיצָה בְּשִׁשִּׁים, וְאֵין בֵּיצָה מִן הַמִּנְיָן.
§ The Gemara continues to discuss the nullification of forbidden foods. Rav Naḥman says: A sciatic nerve that was cooked with kosher food is nullified if the mixture contains permitted food that is sixty times the nerve’s volume, and the sciatic nerve itself is not counted in that number, because it cannot nullify itself. If an udder, which is meat but also contains milk, is cooked with other meat, the milk is nullified if the meat is sixty times its volume, and the udder itself is counted with the rest of the meat. If the egg of a non-kosher bird is cooked with kosher food, it is nullified if the permitted food is sixty times its volume, and the egg itself is not counted in that number, as it cannot nullify itself.
אָמַר רַבִּי יִצְחָק בְּרֵיהּ דְּרַב מְשַׁרְשְׁיָא: וּכְחָל עַצְמוֹ אָסוּר, וְאִי נָפַל לִקְדֵרָה אַחֶרֶת – אוֹסֵר.
Rabbi Yitzḥak, son of Rav Mesharshiyya, says: In the case of an udder cooked with meat, even if the meat is sixty times the volume of the milk, so that the meat is permitted, the udder itself is forbidden, because the meat imparts flavor to the milk contained within the udder, which then renders the udder forbidden. And if the udder subsequently falls into another pot, it also renders the contents of that pot forbidden unless they are sixty times the volume of the udder.
אָמַר רַב אָשֵׁי: כִּי הֲוֵינַן בֵּי רַב כָּהֲנָא, אִיבַּעְיָא לַן: כִּי מְשַׁעֲרִינַן בְּדִידֵיהּ מְשַׁעֲרִינַן, אוֹ בְּמַאי דִּנְפַק מִינֵּיהּ מְשַׁעֲרִינַן?
Rav Ashi said: When we were in the study hall of Rav Kahana, a dilemma was raised before us: When we assess whether the contents of the pot are sufficient to nullify the udder, do we assess whether the pot contains sixty times as much permitted food as the entire volume of the meat of the udder itself, or do we assess only that milk which came out from the udder, since the udder itself has been removed from the mixture?
פְּשִׁיטָא דִּבְדִידֵיהּ מְשַׁעֲרִינַן, דְּאִי בְּמָה דִּנְפַק מִינֵּיהּ – מְנָא יָדְעִינַן? אֶלָּא מֵעַתָּה, נָפַל לִקְדֵרָה אַחֶרֶת – לֹא יֶאֱסֹר?
The Gemara responds: It is obvious that we assess the entire volume of the meat of the udder itself, as if we were to attempt to assess only that which came out of it, how would we know how much came out? The Gemara objects: If that is so, then if the udder falls into another pot, it should not render the food in that second pot forbidden, because it has been assumed that all the milk in the udder has been released into the first pot.
כֵּיוָן דְּאָמַר רַב יִצְחָק בְּרֵיהּ דְּרַב מְשַׁרְשְׁיָא: וּכְחָל עַצְמוֹ אָסוּר, שַׁוְּיוּהּ רַבָּנַן כַּחֲתִיכָה דִּנְבֵלָה.
The Gemara explains: Since Rav Yitzḥak, son of Rav Mesharshiyya, says that even if there is sixty times as much meat in the pot as there is milk in the udder, the udder itself is forbidden, clearly the Sages equated the udder with a piece of non-kosher meat. Consequently, the reason the udder renders the contents of the second pot forbidden is that the udder is intrinsically forbidden, not because of the milk that is released into the pot while it is being cooked.
בֵּיצָה בְּשִׁשִּׁים, וְאֵין בֵּיצָה מִן הַמִּנְיָן. אֲמַר לֵיהּ רַב אִידִי בַּר אָבִין לְאַבָּיֵי: לְמֵימְרָא דְּיָהֲבָה טַעְמָא? וְהָא אָמְרִי אִינָשֵׁי: כִּי מַיָּא דְּבֵיעֵי בְּעָלְמָא!
§ The Gemara addresses Rav Naḥman’s statement that if the egg of a non-kosher bird is cooked with kosher food, it is nullified if the permitted food is sixty times its volume, and the egg itself is not counted in that number, as it cannot nullify itself. Rav Idi bar Avin said to Abaye: Is this to say that the forbidden egg imparts flavor to the food with which it is cooked? But isn’t it true that when people want to indicate that food is tasteless, they say: This is like mere egg-water? This indicates that an egg does not impart flavor.
אֲמַר לֵיהּ: הָכָא בְּמַאי עָסְקִינַן?
Abaye said to him: Here we are dealing with
