Turtle soup

Turtle soup, also known as terrapin soup, is a soup or stew made from the meat of turtles. Several versions of the soup exist in different cultures, and it is often viewed as a delicacy. The principal characteristic of turtle meat is that the broth it is cooked in becomes extremely gelatinous once cooled. Turtle meat has no characteristic taste on its own, so the flavor of turtle soup depends entirely on seasoning. Mock turtle soup is made from other gelatine-producing meat such as calf's head and calf's feet.
