For each serving, split one live lobster. To do this use a sharp pointed knife. Cross the large claws and hold firmly with the left hand. Make a deep incision with the knife at a point between the two large claws and drain knife quickly through the entire length of body and tail. Remove intestinal vein and craw.
For 4 servings, prepare a dressing of 1 1/2 cups cracker crumbs or cracker meal, 1/2 teaspoon salt, moisten with 2 tablespoons Worcestershire sauce, and 1 cup of melted butter. Spread dressing generously in cavity.
For eye-appeal, cut off 4 of the small claws from each lobster and press into the dressing. To preserve moistness, place large lettuce leaves over the dressing. Place lobsters on broiler 8-10 inches from unit and cook 25-30 minutes. Remove lettuce leaves which may have become charred. Serve Maine broiled lobsters with melted butter.
