Apple Tarragon Barbecue Chicken

In a small saucepan, combine all ingredients except chicken. Bring to a boil, reduce heat, and simmer uncovered 15 minutes. Let cool 5 minutes.

Place chicken pieces in a large bowl. Add apple-tarragon marinade, reserving 1 cup. Cover 1 to 3 hours at room temperature turning occasionally, or refrigerate overnight.

Remove chicken from marinade, reserving 1 cup of marinade. While chicken is cooking, simmer reserved marinade to make a sauce.

Grill chicken pieces over medium direct heat, turning, for about 40 minutes, or broil 25 to 30 minutes, until chicken is tender. While chicken is cooking, simmer reserved marinade until it thickens to make a sauce.
