Barbecued Shrimp

2 pounds fresh, unpeeled shrimp
4 stalks celery with leaves, diced
1/2 teaspoon garlic powder
3 lemons, cut into wedges
2 tablespoon cracked black pepper
3/4 cup butter or margarine, cut into cubes
Lemon wedges (for garnish)
2 tablespoons Worcestershire sauce
2 tablespoons salt
3/4 teaspoon hot sauce

Wash shrimp thoroughly and place in a large shallow pan. Add celery and garlic. Squeeze juice from lemons over top. Dot shrimp with butter and sprinkle with remaining ingredients except lemon wedges. Place shrimp under broiler until butter melts and shrimp starts to turn pink (about 5 minutes), stirring several times. When all shrimp are slightly pink, reduce temperature to 350 degrees F and bake 20 more minutes or until done, stirring often. Do not overcook or shrimp will become mushy. Test for doneness.

Garnish with lemon wedges.

Flavor improves if shrimp are cooked ahead of time and then reheated, but do not overcook.
