     1/4  cup           parsley -- minced
   1                    juice and rind of 1 lemon
     1/4  teaspoon      hot pepper sauce
   1 1/2  tablespoons   Worcestershire sauce
     1/2  teaspoon      basil -- ground
     1/2  teaspoon      oregano -- ground
     1/2  teaspoon      cinnamon
   1      tablespoon    bacon fat
   5      pounds        shrimp -- peeled and deveined
                        salt to taste

Preparation:

Combine all except shrimp. Cook, stirring frequently 35-50 minutes. Allow to cool. Refrigerate sauce 1 week to allow flavors to truly blend. Marinate shrimp in sauce a minimum of 1 hour. Arrange shrimp on skewers. Prepare the grill and allow briquettes to burn down to a gray ash. Grill shrimp, basting every minute with left over sauce. Should be done in about 5 minutes. Shrimp are done when the flesh turns from pink to white. Do not overcook as overcooked shrimp are tough and chewy.
