This recipe is best for whole chicken or quarters. That gives you time to baste often in order to lock in these wonderful flavors. Combine the following ingredients:
    2 sticks of butter (NOT margarine)
    2 Tbs soy sauce
    2 garlic cloves - minced
    1 Tbs dijon mustard
    1 Tbs dried parsley
    1/2 tsp tarragon
    1 tsp fresh ground black pepper
    1/2 salt

Mix all of the ingredients in a pan and heat over medium heat. Simmer for 15-20 minutes. Fire up the grill and cook over indirect heat until the internal temperature of the chicken (in the thickest part) reaches 160°. While warm, use the baste every 15 minute while chicken is cooking. Enjoy!
