Johanan at the synagogue of Ma'on of a kid that was roasted with its fat, and on enquiring of R. Johanan he ruled that one may cut away [the meat] and eat it until one reaches the fat! — That was a lean kid.1 R. Huna b. Judah suggested that it was the case of a kidney roasted with its fat, and he [R. Johanan] declared it to be permitted.2 Rabin son of R. Ada said: It was the case of a kilkith3 that was found in a pot of stew, and on enquiring of R. Johanan he ruled that a gentile cook should taste it. 4 Raba said: In the past the following was always a difficulty to me. It was taught: In a pot wherein meat had been cooked a person may not boil milk, and if he did boil [milk] therein, it depends whether the pot imparted a flavour [to the milk] or not.5 [In a pot wherein] terumah6 food [had been cooked] a person may not cook common food, and if he did cook [common food] therein, it depends whether the pot imparted a flavour [to the common food] or not. Now in the case of terumah it is clear, for a priest could taste the food;7 but in the case of meat and milk who may taste it?8 But now that R. Johanan ruled that we can rely upon a gentile cook, in this case too we could rely upon a gentile cook. Raba also said, [In certain cases] the Rabbis ruled that the test whether or not it imparts a flavour applies, and [in other cases] the Rabbis ruled that one may rely upon a [gentile] cook, them. would be relied upon only so long as he is ignorant of the issue that is involved. whether it contains any flavour of the terumah food which had previously been cooked in this pot.
