Ingredients

4 ounces rock shrimp (or peeled medium shrimp, deveined)

1 tablespoon minced shallot

2 teaspoons finely chopped peeled fresh ginger

1 tablespoon mayonnaise

1/2 teaspoon Sriracha (Asian chili sauce) or other chili sauce

1 teaspoon finely grated lime zest, plus 2 teaspoons fresh lime juice

1/2 medium baguette, sliced into 20 thin slices (less than 1/4 inch thick)

3 tablespoons unsalted butter, melted

Preparation

Pulse shrimp, shallot, and ginger in a food processor until a coarse paste forms. Transfer to a bowl. Stir in mayonnaise, Sriracha, and lime zest and juice.

Heat broiler. Working in 2 batches, toast bread slices on a rimmed baking sheet 8 inches from heat source until golden brown, about 30 seconds. Remove from oven. Flip bread, generously brush tops with butter, and spread with a thin layer of shrimp paste (about 1 teaspoon each).

Broil until shrimp mixture is opaque and cooked through and toasts are browned, about 1 minute. Serve warm.
