Nullification: Difference between revisions

#If the forbidden food is recognizable even if its taste is nullified it must be removed. If the forbidden food isn’t currently recognizable but it is possible to remove the forbidden food nonetheless, one should do so. For example, if forbidden fat was cooked into a mixture but it can be removed by pouring water into it and letting the fat rise one should do so.<ref>Rama 98:4</ref> There is a dispute if one needs to do so if in the process the whole mixture will be ruined. Some poskim advise being strict.<ref>Badei Hashulchan 98:55</ref>

#A forbidden food that fell into a mixture of permitted food that shares its taste is nullified biblically as long as there’s a majority and according to the rabbis requires nullification of one to sixty to be permitted. However, if that forbidden food fell into a mixture of permitted food with a different taste than it, it would require nullification of one to sixty on a biblical level. <ref>*The gemara Zevachim 78b explains that a mixture of like ingredients is nullified by majority on a biblical level and nullified by one in sixty on a rabbinic level, whereas mixtures of different types are only nullified even on a biblical level if there’s one in sixty. Why do you need 60 needs to nullified the forbidden food in a mixture of like types? The Rosh (Chullin 7:37) explains that it is a particular prohibition to avoid any confusion between these two categories. However, the Rambam (Machalot Asurot 15:4-5) understands that this rabbinic prohibition was such that a forbidden food is never nullified until it is dispersed in such a great quantity such as one in sixty that it is completely lost. The Badei Hashulchan 98:13 cites this dispute.
