Cold Salmon

Saumon froid (cold salmon) teaches one uncompromising thing: fish served cold stays succulent when it is poached whole and allowed to cool in the liquor that cooked it. Individual portions may look tidier, but their cut faces surrender moisture; the whole fish, still in its silver skin, protects the flesh. That is the dish.

The book assumed a long fish kettle, five quarts of Court-bouillon with Vinegar (No. 163), and a garde-manger, the cold-kitchen cook. Montpellier Butter (No. 153), an herb-rich cold butter sauce, Barquettes (No. 314), little boat-shaped croustades, and cucumber Cassolette cases could all be waiting at hand. Your honest equivalents are a snug metal pan that fits both the fish and the refrigerator, a foil sling, and a sink full of ice. The regiment of aspics and stuffed garnishes is brigade scaffolding and can go; poaching the fish whole and cooling it in the same liquor must stay. One cook, one stove, one evening.

Bring the saumon froid to the table properly cold, its coral flesh moist beneath bright silver skin, with cucumber, capers, anchovy, herbs, and the green sauce beside it. No piped colored butter and no decoration for its own sake. The step that decides everything is the cooling: leave the salmon submerged, then pull the heat out quickly with an ice bath so moisture and safety travel together.
