Côtelettes Froides de Saumon

Côtelettes Froides de Saumon (cold molded salmon cutlets) teach a cold-kitchen principle: temperature is structure. The one true thing to know before touching a pan is that the salmon must remain cold through shaping, and the cooked cutlets must be colder still before the aspic touches them. Cold fish slices cleanly and holds the mold; a cold surface catches the half-set aspic in a clear, even coat.

The original assumed a cold-larder cook beside the saucier, stock never off the fire for clear aspic, drawers of tin cutlet molds, and enough hands to build a tazza with a rice or semolina pedestal. Your home equivalent is honest: small oval molds, prepared clear fish stock strengthened with gelatin, and a shallow serving dish. The pedestal and vertical salad pyramid were brigade scaffolding, so they go. The buttered mold, red salmon lining, seasoned center, dry poach, immediate unmolding, aspic glaze, and sauceboat are the dish, so every one stays. One cook, one stove, one evening.

When finished, each cutlet should look like polished coral beneath a clear glaze, with a few very green peas held neatly on its surface. The decisive moment is the glazing: wait until the cutlets are thoroughly cold and the aspic has thickened to the body of light cream. Too warm or too fluid and it runs straight onto the tray; catch those two temperatures, and the old ball-supper piece belongs entirely at your table.
