Petites Mousses de Homard

Petites Mousses de Homard (little cold lobster mousses) teach the rule that governs every cold mousse: the lobster base must be cool but still fluid when the whipped cream goes in. Fold into warmth and the cream loses its air; wait until the gelatin sets and the mousse becomes pebbled. Catch the interval between them and each little mousse stands above its cassolette, pale coral and light enough to yield under the spoon.

The original entry assumed a garde-manger (cold station) beside a saucier, lobster jelly ready from a stockpot never off the fire, mousse prepared in quantity, silver timbales, paper collars, and beds of ice. This cold hors d'œuvre had no use for a salamander. At home, two cooked lobster tails supply both meat and shells for a quick fond de homard (concentrated lobster stock), powdered gelatin gives a measured set, straight-sided ramekins replace silver, food-safe parchment replaces white paper, and the refrigerator replaces the ice bed. The brigade's prepared components and banquet quantity are scaffolding; the clear jelly base, whipped cream, paper collar, and proud cold set are the dish and must stay. One cook, one stove, one evening.

If the lobster base begins setting before the cream is ready, don't force the fold. Warm it briefly over barely warm water until it flows again, then cool it to the proper point. Ça se rattrape. Bringing that base to cool and fluid before folding is the step that decides the dish.
