Butterflied Barbecue Chicken With Alabama White Sauce

Serves 4. Big Bob Gibson Bar-B-Q in Decatur, Alabama, is famous for this unusual white barbecue sauce. One taste is all you need to become a believer. In the restaurant, freshly smoked chickens are dunked in this sauce before serving. Pulled chicken doused with this sauce also is very good.

1 whole chicken (31/2 to 4 pounds)

Olive oil

Kosher salt and ground black pepper

Alabama white barbecue sauce (recipe below)

1. Prepare a grill for medium heat, indirect cooking. For a charcoal grill, this means banking the hot coals to one side of the grill and cooking on the other side. For a gas grill, this means turning off one or more burners to create a cooler side, then cooking on that side.

2. Use paper towels to pat the chicken dry. Flip it upside down so the breast is on the cutting board. Using kitchen shears, cut along both sides of the backbone so the bone can be removed. Gently but firmly open up the bird a little, then flip it to be breast side up. Break the breastbone by firmly applying pressure and pressing down.

Brush chicken all over with olive oil. Season lightly on both sides with salt and pepper. Place the chicken skin side up on the cooler side of the grill and grill for 20 to 30 minutes, or until beginning to brown.

3. Turn the chicken over and brush barbecue sauce on the back of the chicken. Grill for 10 minutes. Turn back over (breast side up) and brush sauce on skin. Grill for another 20 to 30 minutes, brushing it twice more with barbecue sauce, until the thigh registers 180 F.

4. Remove the chicken from grill. Using a clean pastry brush, brush the chicken one more time with sauce, then let it rest for 10 minutes. Cut the chicken into quarters and serve with extra sauce for dipping.
