Soupe aux Foies de Volaille

Soupe aux Foies de Volaille (chicken liver soup) teaches one true thing: liver becomes silken when it is finely sieved and cooked gently, but coarse and mineral when allowed to boil hard. Done properly, the soup is tawny, glossy, and full-bodied without a drop of cream, with butter-browned liver slices under the spoon and Madeira rising at the last moment.

The old kitchen assumed a saucier on staff, consommé or brown stock never off the fire, a tammy ready for two separate passes, and a salamander elsewhere on the line, though this soup never goes beneath it. At home, a heavy saucepan, a whisk, a small food processor, and a fine-mesh sieve do the honest work. The brigade's continuous service becomes one batch of about two quarts, enough for six to eight bowls. One cook, one stove, one evening.

The tammy cloth and the extra hands were scaffolding, so they can go. The light-brown roux, raw liver sieved into the stock, full fifteen-minute cook, second straining, sautéed liver garnish, bold pepper, and last-minute Madeira are the dish, so they stay. Keep the soup at a bare simmer once the liver enters. That is the step that decides everything.
