In many organisms sex is determined genetically. Often this is accompanied by chromosomal differences between the sexes. Chromosomes, structures made of proteins and coiled DNA, contain all the genetic information of an organism.
What Are Sweetbreads? ccording to the Larousse Gastronomique, sweetbread is the culinary term for the thymus gland (in the throat) and the pancreas (near the stomach) in calves, lambs and pigs. Larousse further states that thymus sweetbreads are elongated and irregular in shape while pancreas sweetbreads are larger and rounded. But sweetbreads are neither sweet, nor are they bread. The word sweetbread was first used in the 16th century, but the reason behind the name is unknown.
Sweetbreads, though mild in flavor, have an offal-reminiscent flavor somewhat akin to brain. People often describe the texture as tender and creamy; I would add marginally juicy.. 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.They get crispy on the outside and stay soft inside, while the interior is almost ripe, bursting with meat juice. Make sure you remove the membrane from the organ when you bring home your pound(s) of sweetbreads.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.
