COOK'S ILLUSTRATED GRILLED LEMON-PARSLEY CHICKEN BREASTS ON A CHARCOAL GRILL

Steps:

• 1. Whisk together mustard, 1 tablespoon lemon juice, 3 tablespoons olive oil, parsley, 1/4 teaspoon sugar, 1/4 teaspoon salt, and 1/4 teaspoon pepper in small bowl; set aside. 2. Whisk together remaining tablespoon lemon juice, remaining 3 tablespoons olive oil, remaining teaspoon sugar, 1 1/2 teaspoons salt, 1/2 teaspoon pepper, garlic, and water in medium bowl. Place marinade and chicken in gallon-size zipper-lock bag and toss to coat; press out as much air as possible and seal bag. Refrigerate 30 minutes, flipping bag after 15 minutes. 3.Build modified two-level fire by arranging all coals over half of grill, leaving other half empty. Grill is ready when side with coals is medium-hot (you can hold your hand 5 inches above grate for 3 to 4 seconds). 4. Remove chicken from bag, allowing excess marinade to drip off. Place chicken on cooler side of grill, smooth-side down, with thicker side facing coals. Cover with disposable pan and cook until bottom of chicken just begins to develop light grill marks and is no longer translucent, 6 to 9 minutes. Using tongs, flip chicken and rotate so that thinner side faces coals. Cover with disposable pan and continue to cook until chicken is opaque and firm to touch and instant-read thermometer inserted into thickest part of chicken registers 140 degrees, 6 to 9 minutes longer. 5. Move chicken to hotter side of grill and cook, uncovered, until dark grill marks appear, 1 to 2 minutes. Using tongs, flip chicken and cook until dark grill marks appear and instant-read thermometer inserted into thickest part of chicken registers 160 degrees, 1 to 2 minutes longer. Transfer chicken to cutting board, let rest, tented with foil, 5 minutes. Slice each breast on bias into 1/4-inch-thick slices and transfer to individual plates. Drizzle with reserved sauce and serve.
