- Question: Why is taste of chometz absorbed in food more stringent than taste of chometz absorbed in a vessel on Pesach?
A. The Rema (467:10) holds that we have a custom to burn a chicken which has a cracked kernel of wheat found in it, and you can’t leave it until after Pesach even though the physical chometz was removed and only the taste is absorbed in the chicken.
B. The Shulchan Aruch (451:1) says that any earthen ware vessels that chometz like oatmeal, which one uses throughout the year should be washed off of all physical chometz and put away until after Pesach. The Mishna Berura (2) says this applies to any other type of vessel if you don’t want to kasher them.
C. The Chazon Ish (Orach Chaim 117:15) says that technically one does not have to sell any chometz which is absorbed in vessels though he does include them in the language of his document of selling chometz as a stringency to get rid of every last bit of chometz.
D. The Chazon Ish says that really absorbed taste of chometz cannot be sold because it has no physical substance to it but since the taste can come out of the wall of the vessel it can be considered physical so he stringently sold it but Rav Elyashiv and the Shulchan Aruch HaRav both say as long as there aren’t any physical chometz on vessels they don’t have to be sold before Pesach.
E. The Chazon Ish in note 12 said that absorbed taste in a vessel is like chometz which was left in rubble which isn’t edible.
Answer: The Dirshu Mishna Berura (451:1:2:2) quoting the Chazon Ish answers that taste of chometz absorbed in food is different from taste absorbed in vessels since it is still edible in food even though it is not physically there but when eating the chicken for example it is like you would eat the chometz absorbed inside it, with it, so it should be burned according to the Rema except in extenuating circumstances.
