(46) The reason is that once the required salting time has passed, the tzir is not considered to be roseiach. According to Rashi if one cut the meat after the required salting time it needs only to be washed, for the tzir is considered as a cold substance now, not roseiach, but the Mechaber requires purging.
(47) The reason is that the tzir coming from the meat after the salting time is as any liquid. Even though the salt on the meat is forbidden for it is mixed with blood, nevertheless, the blood dries up into the salt and has no strength to be absorbed into the meat, as well as the fact that the salt has no strength after the salting period. This is all in a case of great loss, if not, one should not be lenient for many are of the opinion that the salt is still considered roseiach.
(48) But the Rashal holds that whatever is in the tzir is absolutely forbidden. He also says that if this piece is mixed with others it doesn’t need sixty, only a majority to be nullified. It is a case where one may rely on Rashi who is lenient in any case.
(49) For the vessel will easily absorb since it has nowhere to go.
(50) This is even if it is not dirty. As long as the dairy vessel is ben-yomo, it is forbidden
(51) Meaning that in a case of great loss one may be lenient as in the first opinion that doesn’t consider the tzir roseiach after the salting period.
(52) This is difficult to understand for even the first opinion in the Mechaber, which is Rashi’s view, one must wash the meat well after salting. Therefore, why did he write this law as being according to the one that forbids it? One must say that according to Rashi one need not wash the meat off right away, and it may even be put it into a vessel without holes until one is ready to cook it and then wash it. However according to those who forbid it for it is considered as roseiach one must immediately wash the meat before placing it into a vessel without holes, but this is not mentioned in the words of the Mechaber.
(53) It seems that the knife is permitted even if cut during the sailing time because the blood will flow off. This poses a difficulty based on section 17 where it should be permitted even in a vessel with holes based on this, and nevertheless the Rema forbids it! This requires further study.
