1 1/2 tablespoons Worcestershire sauce
1 1/2 tablespoons Dijon mustard
1 1/2 tablespoons Old Bay
1 large egg, lightly beaten
kosher salt and freshly ground black pepper, to taste
1 1/2 pounds jumbo lump crab meat
4 tablespoons unsalted butter
2 tablespoons finely chopped pickles
1 teaspoon finely chopped parsley
1 lemon, zested and juiced, plus wedges, for serving
1 small shallot, minced
Heat the oven to broil or heat the oven to 450°F. Place 1 tablespoon of butter on the top of each crab cake and broil or bake until golden, about 3 to 5 minutes under the broiler or 10 minutes in the oven. Transfer to a platter.
Meanwhile, in a small bowl, combine the remaining 1/2 cup mayonnaise with the capers, pickles, parsley, lemon zest and juice, shallot, salt, and pepper. Set tartar sauce aside.
Serve cakes with tartar sauce on the side, or for sandwiches divide the crab cakes between the buns and top with a few slices of tomato, lettuce, and the tartar sauce.
