   1      medium        chicken (about 3 pounds)
   4      teaspoons     white vinegar
                        salt
   4      teaspoons     lemon juice
   3      inches        peeled -- fresh ginger
   2      medium        onions
   1      bulb          fresh garlic
   1      pound         plain yogurt
   1      teaspoon      red pepper
   2      teaspoons     garam masala
   1      teaspoon      black pepper
   2      tablespoons   butter or margarine

Preparation:

Meat should be at room temperature. Cut into serving-sized portions. Remove all skin and fat. Use a sharp knife to slash chicken pieces in several pieces (cut through to the bone). Mix vinegar with salt and lemon juice. Coat the chicken with the vinegar mixture. Make a paste of ginger, onions and garlic in a mortar or food processor. Combine yogurt with onion paste, red pepper, garam masala and black pepper. Stir well to combine and add chicken. Cover and marinate at least 1 day, try 2 days. Let the chicken come to room temperature before grilling or baking at 350F. for 40 minutes. Use melted margarine to drizzle over chicken as it cooks. Serve on a bed of rice. The marinade can be used again.
