and fish were in a basin, and boiling water was poured on them, they are not
forbidden even though the boiling water cooked the surface of the meat and
fish. The reason that the meat and fish are not forbidden is that Chazal did

together does not exist in these times.

together, they formed a forbidden mixture. We are inclined to be machmir and

meat without washing his hands, the meat is not forbidden. We assume that
