Coulis

n. sauce made of mashed raw or cooked fruit or vegetables

A coulis (pron: coo-lee') (French, from Old French couleis, from Vulgar Latin cōlāticus, from Latin cōlātus, past participle of cōlāre, to strain) is a form of thick sauce made from puréed and strained vegetables or fruits. A vegetable coulis is commonly used on meat and vegetable dishes, and it can also be used as a base for soups or other sauces. Fruit coulises are most often used on desserts.  Raspberry coulis, for example, is especially popular with poached apples.
