Preparation Stir together crabmeat, mayonnaise, scallions, egg, Worcestershire sauce, mustard, cayenne, 1/4 teaspoon salt, and 3/4 cup bread crumbs in a bowl until just combined. Form into 4 (1-inch-thick) patties (3 1/2 inches in diameter; patties will be soft but will firm up when fried). Spread remaining cup bread crumbs on a plate, then dredge patties in crumbs, knocking off excess, and transfer to a platter. Heat oil in a 12-inch heavy skillet over medium heat until it shimmers, then fry patties, turning over once, until golden, 5 to 6 minutes total. Transfer to paper towels to drain. Assemble burgers with buns and accompaniments. Cooks' note:Patties can be formed, without bread-crumb coating, 12 hours ahead and chilled, covered. Dredge in bread crumbs just before frying.
