Purée de Choux de Bruxelles, otherwise Flamande

Purée de Choux de Bruxelles, dite Flamande (Brussels sprout purée, Flemish style) teaches the discipline behind every green vegetable purée: freshness first, gentle heat second, machinery last. The one true thing to know before touching the pan is that no sieve can restore a tired sprout. Begin with compact, bright heads, parboil them briefly, and the finished soup will be silken, pale green, and sweet with butter rather than loud with cabbage.

The original assumes a stock never off the fire, a saucier on staff, a tammy for passing the vegetables, and another hand free to skim the pot. At home, prepared white chicken consommé, a food mill or brief immersion blending, and a fine-mesh sieve do the same honest work. Its one-pound formula already finishes at a sensible home scale, about two quarts, so the proportions remain intact; only the milk, finishing butter, and bread garnish have been measured where the entry trusted the saucier's hand. One cook, one stove, one evening.

A dedicated skimmer is brigade scaffolding; skimming the soup clean is not. The brief parboil, the butter stew, the potato liaison, and the milk finish are the dish itself, and all four stay. Guard that first cooking closely, because bright sprouts can be cooked tender later, but olive sprouts never turn green again.
