Grilled Burgers

Build a single-level fire. Set grill rack in place, cover grill with lid, and let rack heat up, about 5 minutes. Meanwhile, break up chuck to increase surface area for seasonings. Sprinkle salt and pepper over meat; toss lightly with hands to distribute seasonings. Divide meat into four equal portions and shape into burgers. Grill burgers, uncovered, over hot fire, turning once and cooking to desired doneness as follows: 3 minutes per side for rare, 4 minutes per side for medium-rare, 5 minutes on the first side and 4 minutes on second side for medium, and 5 minutes per side for well-done. Serve immediately.
