Shrimps and Prawns (Crevettes Grises et Crevettes Roses)

Crevettes grises et crevettes roses teaches a small but fundamental rule: choose shellfish by the work its texture and shell can do. Larger pink prawns give a clean, handsome bite for a cold hors d’œuvre. Tiny grey shrimps surrender their deeper, shell-borne savor to beurre de crevettes grises (grey-shrimp butter). Do not treat them as interchangeable before touching the pan.

The source is a pantry direction rather than a composed formula. Its professional kitchen assumed a garde-manger, the cold-pantry station, with enough hands to send pink prawns into aspics, Mousses, and small cold Soufflé preparations while grey shrimps moved toward garnishes, soups, creams, and butter. For one cook, one stove, one evening, those routes become one coherent hors d’œuvre: gently poached pink prawns, a crock of sieved grey-shrimp butter, and crisp baguette. The multiple preparations and brigade quantities were scaffolding, so they go. The pounding and sieving stay, because they are the dish.

The entry supplies uses rather than proportions, so this home formula adopts the classical working ratio of equal weights grey shrimp and butter. A small processor replaces the mortar, but the tamis, a drum sieve, becomes an ordinary fine-mesh sieve rather than disappearing. Pass the butter through while it is pliable. That single step removes the shell grit and decides whether the finished spread is silk or rubble.
