DIRECTIONS

In medium-size bowl or resealable plastic bag, combine vinegar, oil and tarragon. Whisk or shake until blended. Marinate chicken in mixture for 30 minutes.
    Grease grill lightly with oil; place chicken on grill about 4 in. from hot heat. Turn and baste frequently with marinade mixture until chicken feels springy to touch, about 15 to 18 minutes.
    While chicken cooks, whisk together sauce ingredients in saucepan. Cook over medium-low heat, stirring constantly, until thickened and smooth, for about 5-7 minutes.
    When chicken is done, place sauce in a pool on warm platter; place chicken on top of sauce. Garnish with a few fresh berries and a sprig of fresh tarragon. Yield: 4 servings.
