Salted food, that one is unable to eat because of its salt, which is the amount of salt that [is required] to salt [meat to cook] in a pot, and it stays there the amount of time [required] to salt [meat to cook] in a pot, as long as it is not rinsed, it has the status of food that one is unable to eat because of its salt. Rema: And there are those that say that after it stays in the salt the amount [of time necessary] for salting it is afterwards not called hot food. And for a great need, for example in a case of great loss and it is needed for a feast made for a mitzvah, there is what to rely on the lenient [opinions]. But without this, one shouldn't be lenient at all. Even if the meat was not salted on both sides, only on one side, as long as it was salted [to the point of] salted food that one is unable to eat because of its salt, it is considered hot food. But anything that's not salted so much is considered cold, even if it was salted on both sides. And there are those that say that we are not experts in the matter and we should consider even [the amount needed] to salt for roasting to be like heated. And is is good to be stringent in a case where there is no great loss. And a salting that's similar to the salting [one would do for food] that he needs to take for a long trip, even after it's rinsed it's considered food that can't be eaten because of its salt, and as long as it's not soaked in water it has the law of hot food which forbids [when touching certain other foods] up to [an amount] that needs to be peeled away. And there's no difference whether the salted food is on top and the unsalted food is on the bottom or whether the salted food is on the bottom and the unsalted food is on top, always the salted food imparts taste to the unsalted food and it does not absorb taste from it. Therefore, meat and cheese that were both salted that touched each other, one is required to peel away the place from both of them where they touched. And if one of them is salted and the second is unslated, the salted food is permitted with a rinsing and the unsalted food requires peeling away. Rema: And there are those that say that with all salted foods we require a measure of sixty times [in order to permit the foods], and see later on in chapter 105 how we are accustomed to rule. And that which we said that if the salted food was pure and the unsalted food was impure that [the pure food is] permitted, that's where the impure food was dry, but if it's a wet item it forbids the pure food, for after it's [salted to the extent of a food that] one is unable to eat because of its salt, it absorbs from the forbidden food that's near it and they both become forbidden. And this is precisely where the pure food is [at least] slighly moist, but if it's completely dry it does not absorb from the moist food near it. And if they are both dry, even if they are both salted, or if they are both moist but not because of salting, it is enough [to permit them] with rinsing. Rema: Al meat juices from meat that was salted, even if it was only salted [to the extent required] for roasting, it's considered like hot food. And therefore, if meat juices fell on cheese or onto a vessel, it forbids it. Even in a case where the meat wouldn't forbid because it's not considered like hot food, nevertheless, the meat juices are considered like food that one is unable to eat because of its salt. And meat juices of meat that forbids that fell onto a vessel, [the vessel] requires being immersed into boiling water. And if it's an earthenware vessel, it requires breaking it. And if it only fell onto one area, and the vessel is wood or something similar, one can peel away that area and that's enough.

An olive-worth of meat that falls into a pot of boiling milk: let a non-Jew taste the dish. If he says that there is a taste of meat in it, it is forbidden. If not, it [the milk] is permitted, even in less than sixty, and that piece [the meat] is forbidden. When is this true? When one quickly removes the piece before it exudes the milk that it absorbed, meaning before the pot rests from its boiling. But if he didn't remove it before it was able to exude the milk it absorbed, even if a non Jew tastes it and it has no taste at all, (Rama) it's forbidden unless there is sixty. See chapter 98 (Shulchan Arukh, Yoreh De'ah 98) that we aren't accustomed to rely on the tasting of a non-Jew and we need sixty every time.

A non-permissible [food item] that was mixed with a permissible item that is not of its type, for example prohibited fat that was mixed with meat, a non-Jew should taste it, if [the non-Jew] says that it has no fat taste or if he says that it has taste but the taste is "pagum" (somehow not good), permitted. And this is that it is not for the ends of improving. And it must be that [the non-Jew] doesn't know that he is being depended upon. And if there is not there a non-Jew to taste it, we measure it against 60. And likewise, if it is a [mixture of two things which are] of the same type, because one cannot really upon taste, it is measured against 60. {REMA: It is not done now to trust a non-Jew, and we measure against 60.}
