Coquilles Saint-Jacques (French Scallop Gratin with Gruyere)
Tender scallops, a light cream sauce, and a crisp Gruyere and breadcrumb crust all land on the same spoon. Scallops toughen quickly, so the pan sear is brief and the oven finishes the warming. Reducing the white wine by half concentrates its acidity, and with cream and lemon juice the sauce stays bright instead of heavy. Any surface moisture on the scallops turns to steam and blocks browning, so they are pressed thoroughly dry first. Bake and serve them in ramekins or scallop shells, with baguette for the leftover sauce.
