Parfait de Foie Gras

Parfait de foie gras (smooth preserved duck or goose liver) teaches the rarest classical lesson: sourcing can be the technique. The one true thing to know before touching a pan is that the source tells you not to make it. Fresh foies gras suffered in transport, while the specialist preserving houses worked beside the supply and knew exactly how to handle it; the better result came sealed in its crock.

The book around this entry assumes a saucier, a stock never off the fire, a salamander, and quantities meant for a brigade. This entry calls on none of them. All that scaffolding goes, and what remains is its judgment: buy a fine ready-made parfait, then serve it properly. No formula, seasonings, or ratios are supplied, so none are invented here. One 6.3-ounce crock gives four generous appetizer portions, which changes only the scale of service. One cook, one stove, one evening, and the stove merely warms the bread.

Temperature decides the dish. Straight from the cold, the fat is mute and waxy; left out too long, the parfait slumps and smears. Give it fifteen minutes, use a warm dry blade, and serve while the center remains cool. That small act of attention is the cooking tonight.
