Classic blanquette de veau with mushrooms, pearl onions and cream-yolk liaison
Blanquette de veau depends on restraint. Unlike a browned veal stew, the meat begins in cold water and stays pale as it comes slowly to a simmer. Foam is skimmed, aromatic vegetables are added, and the shoulder cooks gently until fork-tender. This produces both tender meat and a light broth that can become the body of the sauce without carrying roasted colour or flavour.
The garnish is treated with the same pale approach. Button mushrooms are cooked gently without a dark crust, while pearl onions soften in a little broth. The sauce starts with a white roux: butter and flour are cooked long enough to lose rawness but not long enough to tan. Hot strained broth is whisked in gradually and simmered until the sauce coats the back of a spoon with a clean, thin film.
The final liaison is where temperature matters most. Cream and pasteurized egg yolks are tempered with hot sauce, then returned to the pan and heated gently to about 75 °C without boiling. Pasteurized yolks are used precisely because the sauce is not subjected to a hard boil after they enter. Lemon is added at the end with the veal and garnish, giving lift to a sauce that should remain pale, smooth and silky rather than curdled.
