Weighty Matters, Not to be Taken Lightly

Those who don’t learn from the past are doomed to repeat it. A few summers ago, a non-kosher supermarket in Long Island City purchased a used scale for its meat department. The scale had been previously used in a kosher butcher shop. The scale was pre-programmed to include Shechitas Bais Yoseph. Lo and behold the…

Kli el Kli B’lo Rotaiv – Lo Basi Ela L’Orer

Tosfos (Chulin 108a tipas chalav) writes that if a drop of milk fell into a pot of meat, although it gives ta’am into the piece of meat that it touches, this ta’am will not transfer into other pieces of meat, even though they are touching, provided the first piece of meat is completely above the…

Milk from Non-Kosher Species and its Relationship with the US Kosher Dairy Industry

CHaNaN Lach B’Lach

by Rabbi Eli Gersten The Mordechai (Chulin 697) writes that we do not say Chaticha na’ases neveila regarding sha’rissurim lach b’lach. Only when a chaticha (solid) absorbs issur, do we say that because of its chashivus, the entire mass is transformed into issur. But if liquid heter and issur are combined, the issur will remain…
