But if only the flavor of the forbidden food is recognizable in the mixture, but not its substance, as it was completely dissolved into the permitted food, the mixture is forbidden, but one is not flogged for consuming it. And if the forbidden food amplified the flavor of the permitted food to its detriment, it is permitted.

The Gemara asks: But then let Rabbi Yoḥanan say: If the forbidden food imparts flavor to the detriment of the mixture, it is permitted. Why does he use the term: Amplified? The Gemara answers that this is what Rabbi Yoḥanan teaches us: That even if there are other substances that detracted from the flavor of the mixture along with the forbidden food, e.g., insufficient salt or excessive seasoning, this is not taken into consideration; since the forbidden food detracted from its flavor, the mixture is permitted. The Gemara comments: And the halakha is in accordance with the last version of the statement of Reish Lakish.

§ Rav Kahana says: From the statements of all the amora’im who were cited, namely, Shmuel, Rabbi Yoḥanan, and Reish Lakish, we learn that if a forbidden food imparts flavor to a permitted food to the detriment of the mixture, it is permitted. Abaye said to him: Granted, from all the rest of them this conclusion is very well; but how can this be concluded from the statement of Reish Lakish? He says only that the Sages said that if a forbidden food imparts flavor to a permitted food to its detriment, the mixture is permitted. Perhaps he is only citing what others said and he himself does not hold accordingly.

The Gemara asks with regard to Rav Kahana’s statement: By inference, is there one who says that if a forbidden food imparts flavor to a permitted food to the detriment of the mixture, it is forbidden?

The Gemara answer: Yes, and this opinion is taught in a baraita: Both in a case where the forbidden food imparts flavor to the detriment of the flavor of the permitted food, and in a case where it imparts flavor that enhances the permitted food, the mixture is forbidden; this is the statement of Rabbi Meir. Rabbi Shimon says: If it enhances the flavor it is forbidden, but if it causes it detriment it is permitted.

The Gemara explains: What is the reasoning of Rabbi Meir? He derives this halakha from the case of vessels of gentiles that require purging, i.e., vessels that gentiles used for cooking, which the Torah requires that one purge through fire and ritually purify before they may be used by Jews (see Numbers 31:22–23 and mishna on 75b). Is it not the case that vessels of gentiles that require purging impart flavor to food that is cooked in them to their detriment? Since time has passed since the gentiles cooked non-kosher food in the vessels, the flavor that the vessels transmit to food that a Jew cooks in them is certainly detrimental, and yet the Merciful One deems their use prohibited without purging. So too, the case here is no different, and even if the flavor imparted by the forbidden food is a detrimental one, the mixture should be forbidden.

And the opinion of the other tanna, Rabbi Shimon, who deems the mixture permitted if the flavor imparted is detrimental, can be explained in accordance with the opinion of Rav Huna, son of Rav Ḥiyya; as Rav Huna, son of Rav Ḥiyya, says: With regard to the vessels of gentiles, the Torah prohibits only a pot that was used for cooking on that very day, which does not yet impart flavor to the detriment of the food cooked in it. Rather, the flavor that it imparts is not considered detrimental. And the opinion of the other tanna, Rabbi Meir, can also be explained in accordance with this statement, as in his opinion, even in the case of a pot that was used for cooking on that very day, it is not possible that it does not detract from the flavor of food that is subsequently cooked in it even slightly.

The Gemara asks: And what is the reasoning of Rabbi Shimon? It is as it is taught in a baraita that from the verse: “You shall not eat of any unslaughtered animal carcass; you may give it to the resident alien [la’ger] who is within your gates, that he may eat it” (Deuteronomy 14:21), it is derived that with regard to animal carcasses, anything that is fit for a ger toshav to consume is called an unslaughtered carcass and is forbidden,
