En blanquette is a term used for any white meat cooked in a white stock or water. A classic blanquette de veau is usually made with veal breast or shoulder. You can buy the meat in chunks at butcher counters.
The meat is stewed with a mirepoix, then strained out; the broth is mixed with a roux, white wine, cream and an egg yolk and thickened.
According to purists, only mushrooms and white or pale vegetables (celeriac, celery hearts, braised parsnips, lettuce or leeks) are allowed in a blanquette, but nearly everyone adds carrots for extra flavour and to jolly things up. Most serve it on top of riz à la créole (boiled rice).
