Soufflé aux Épinards aux Truffes

Soufflé aux Épinards aux Truffes (spinach soufflé with truffles) teaches that lift begins before you whisk an egg white: the spinach must surrender its water. A wet purée weighs the batter down; a dry, butter-glossed one gives the eggs something light enough to carry. Done properly, it rises deeply green beneath a bronzed crown, with black truffle opening across the top in a fine lattice.

The source entry is terse because it expects the preceding spinach soufflé formula to be in the brigade cook's hands; its new instruction is the lattice of fine truffle slices in place of anchovy. A saucier, a stockpot never off the fire, and a salamander were ordinary brigade supports, yet none performs the essential work here. At home, a saucepan builds the roux-bound base, one 1½-quart dish replaces the large timbale, and four ramekins stand honestly for the small cassolettes. The quantity changes because four people are eating, not forty. One cook, one stove, one evening.

The brigade's staging can go. The dish itself cannot: real butter, a firm roux, spinach dried with patience, egg whites folded gently, and the truffle lattice laid just before baking. Before you meet the whisk, dry the spinach until your spoon leaves a clean trail across the pan. That is the step that decides the soufflé.
