Rub oil and crushed garlic cloves over turkey, then sprinkle with allspice and seasoned salt. Tie or skewer legs together to hold shape during cooking. Cover with aluminum foil.
Bake for 4 hours, or about 20 minutes per pound. Meat thermometer should read 180° F. when inserted into the thickest portion of the breast away from the bone. Remove foil during last 30 minutes of cooking, baste with pan juices and brown skin.Servings: 12
