Caul fat, also known as lace fat, mesentery, crépine or fat netting, is the thin membrane which surrounds the stomach internal organs of some animals, such as cows, sheep, and pigs, also known as the greater omentum. It is used as a casing for sausages, roulades, pâtés, and various other meat dishes. Examples of such dishes are Swiss atriau, French crépinette, Cypriot sheftalia, English faggots, and Italian fegatelli. In the traditional Ukrainian and Russian cuisine, caul fat, known as salnik or salnyk, was usually filled with kasha and liver, and baked in a clay pot in the Russian oven.
