                        ***tarragon marinade***
   1      cup           olive oil or canola oil
     1/2  cup           cider vinegar
   1      tablespoon    minced fresh parsley
     1/2  teaspoon      dried tarragon
     1/4  teaspoon      black pepper -- freshly ground
   2                    bay leaves
                        ***double mustard sauce***
   1      cup           mayonnaise
   1      tablespoon    stone-ground mustard
   1      teaspoon      dry mustard
   1      teaspoon      drained capers
     1/4  teaspoon      black pepper -- freshly ground
   1                    scallion -- minced

Preparation:

Slice the chicken into finger-shaped pieces 1/2 inch by 3 to 4 inches. For the marinade, mix together oil, vinegar, parsley, tarragon, pepper, and bay leaves. Divide chicken between two large self-sealing plastic bags. Add marinade and seal bags securely. Turn bags several times so that all chicken pieces are coated with marinade. Set bags in a bowl and marinate in refrigerator for 3 to 4 hours, turning occasionally. While chicken is marinating, prepare sauce. Spoon mayonnaise into a small bowl. Mix in remaining ingredients. Cover and refrigerate. Prepare the grill and when coals are hot, drain chicken and discard marinade. Set chicken on grill rack about 4 to 6 inches from heat source. Remove the sauce from the refrigerator so it can warm to room temperature. Cook chicken for 6 to 8 minutes, turning once or twice, as necessary. Chicken will char, and juices will run clear when meat is pierced with a fork. Do not overcook. Recipe Source: "APPETIZERS ON THE GRILL" by Barbara Grunes
