Coquilles Saint-Jacques en coquille: preparing scallops in the shell

The preparation of the scallop in its own shell belongs to the coastal kitchens of Brittany and Normandy, where the great scallop of the Channel is landed in winter. It passed into the classical repertoire through the professional kitchen, and the Roux brothers teach it as a matter of opening, cleaning and trimming the animal with method before any cooking begins. The shell serves as both working vessel and dish, and the technique sits within the French tradition of cooking shellfish in their own packaging.

The animal is the great scallop, Pecten maximus, called coquille Saint-Jacques, taken as the white adductor muscle (la noix) with the orange coral attached. The cook opens the shell with a knife along the flat upper valve, severs the muscle from the shell, and detaches the noix and coral from the mantle and the dark viscera, which are discarded. The noix and coral are washed briefly and dried, and the deep rounded valve is scrubbed to serve as the receptacle for the cooked scallop.

The sweet, close-textured noix is served with butter-based sauces, a light cream sauce, or a simple seasoning of lemon, and the coral is kept for its richer, mineral flavour. A dry white wine of good acidity, such as a Chablis or a Muscadet sur lie, cuts the richness of butter and answers the natural sweetness of the flesh. The acidity refreshes the palate between mouthfuls, which is why the pairing holds.
