Velouté Marie Louise

Velouté Marie Louise (poultry velouté enriched with barley cream) teaches the difference between body and binding. Crème d’Orge (No. 712) gives the soup its round, grain-softened body before the liaison enters; the liaison, a final binding of yolks and cream, supplies silk rather than weight. Know one thing before touching the pan: once the liaison is in, the soup must never boil.

The original formula assumed a saucier on staff, prepared poultry velouté and white consommé beside a stockpot never off the fire, and a tammy ready for sieving. There is no salamander work here; the luxury was the stock fire and the extra pair of hands. At home, three measured foundations, a fine-mesh sieve, and one heavy saucepan make a generous two quarts. The brigade's hot-holding and relay of cooks can go. The formula's two-to-one-to-one ratio, the sieving, the gentle heat, and the last-minute finish must stay. One cook, one stove, one evening.

Done properly, Marie Louise is pale ivory and perfectly smooth, with a quiet butter sheen and tiny tender dice of macaroni beneath the surface. The finish decides it: temper the liaison slowly, keep the heat below a simmer, and mount the butter only after the pan leaves the stove.
