Blanquette de veau à l'ancienne. Blanquette de veau ([blɑ̃kɛt də vo]) is a French veal ragout in which neither the veal nor the butter is browned in the cooking process. To refrain from browning meat and fat in this way, is to cook them en blanquette. From Larousse Gastronomique BLANQUETTE: the french term for a ragout of white meat (veal, lamb or poultry) cooked in a white stock or water with aromatic flavorings. Theoretically, the sauce is obtained by making a roux and adding cream and egg yolks.
