what is sweet breads
Sweetbreads made from an animal's pancreas and thymus glands (called the heart sweetbread and throat sweetbread, respectively). Heart sweetbreads are usually slightly larger, but they taste the same and are cooked the same way.o do this, simmer the sweetbreads so they firm up and are barely cooked through. Then, with your fingers and a sharp knife, peel away the membrane, the gristle, the tubes, and other animal-like bits you'll find in the glands.
