Ingredients

　　1/2 pound sea scallops

　　1/4 cup mayonnaise

　　1/4 cup freshly grated Gruyère

　　1/2 teaspoon Dijon-style mustard

　　1 teaspoon fresh lemon juice

　　1 tablespoon finely chopped fresh parsley leaves

　　1 large egg white

　　8 slices of homemade-type white bread, toasted lightly, the crusts discarded, and each slice cut into 4 squares

　　In a saucepan combine the scallops with enough salted water to cover them completely, bring the water to a simmer, and poach the scallops for 5 minutes. Drain the scallops well and cut them into 1/2-inch pieces. In a bowl whisk together the mayonnaise, the Gruyére, the mustard, the lemon juice, the parsley, and salt and pepper to taste, add the scallops, and toss the mixture well. In a small bowl beat the egg white until it just holds stiff peaks and fold it into the scallop mixture gently but thoroughly. Top each bread square with a heaping teaspoon of the scallop mixture, arrange the puffs about 1/2 inch apart on baking sheets, and broil them under a preheated broiler about 6 inches from the heat for 1 to 2 minutes, or until the toppings are bubbling and lightly golden (do not allow the edges of the toasts to burn).
