Puréed Vegetable Soups

Puréed vegetable soups are potages, created by cooking liquid and fresh or dried vegetables together and then puréeing the mixture to thicken it to a smooth, viscous consistency. Occasionally, the soup is bound with the puréed vegetables, as well as a starchy element such as rice. Classically, however, no puréed soup would be bound with flour. Just before serving, unsalted butter or egg yolks can be added to enrich the soup.
