Côtelettes de Homard Arkangel

Côtelettes de Homard Arkangel (cold moulded lobster cutlets) teach the discipline of the cold mousses: temperature is structure. The one true thing to know before touching a pan is that every element must be properly cold, while the coating must remain fluid enough to flow and thick enough to cling. Lobster and caviare form the salpicon, a finely diced mixture, held with an equal weight of Mousse de Homard (No. 956); the set shapes then wear chaud-froid, a chilled velouté coating, followed by clear aspic.

The original assumed a saucier on staff, a fish stockpot never off the fire, prepared jelly waiting in the cold room, and ranks of metal cutlet moulds. At home, one small saucepan builds the sauce, powdered gelatin gives clean and predictable setting, and shallow silicone moulds or a lined tray make the cutlet shapes. The permanent stockpot and multiple moulds were brigade scaffolding and can go. The proportions cannot: lobster and caviare remain equal by weight, and their combined weight is matched by the mousse. One cook, one stove, one evening.

When the côtelettes are right, their coating is smooth and ivory-pink, the black truffle shows beneath a glass-clear glaze, and the first cut reveals distinct pieces of lobster and caviare held in a tender mousse. Chill the moulded salpicon thoroughly, then cool the chaud-froid until it falls from a spoon in a slow, broad ribbon. That coating point decides the dish.
