A purée refers to the process of reducing a food, such as a fruit or vegetable, to a spreadable form by pounding or the use of liquidiser. Purées are the basis of many soups. A vegetable soup may be slightly thickened by the use of potatoes, lentils, toast or rice. These may be transformed into a velouté by replacing these thickening agents with velouté sauce or into a crème by replacing them with béchamel sauce.
