BISK, or BISQUE, in Cookery, a rich sort of broth or soup, made of pigeons, chickens, force-meat, mutton-gravy, and other ingredients. The word is French, formed, as some think, from biscotta; because the bisque, consisting of a diversity of ingredients, needs several repeated coctions to bring it to perfection. There is also a demi-bisque, made at a low expence, in which only half the ingredients are used; and a bisque of fish, made of carps minced with their roes and lobsters.
