1 pound ground chuck (20% fat) Do not substitute other types of ground beef.
1/4 teaspoon salt
Prepare right before grilling – not ahead of time. Get your grill or burner hot before beginning.
Put the ground beef in a bowl. Lightly break up the meat with your hands and sprinkle evenly with the salt. (Note: use only 1/4 teaspoon. This much helps prevent loss of the burger juices and keeps the burgers from following apart. However, too much salt causes the beef to congeal.)
After you’ve seasoned the meat, divide it into 4, and with lightly cupped hands, shape into patties. As soon as the patties hold together, stop! Over handling will cause the beef to become rubbery when cooked.
Make a shallow indentation in the center of each patty. This keeps the burger flat and prevents the formation of a “bubble burger” when cooking.
Gas Grill Prep: Turn the grill on. Scrape off any debris with a grill brush. Grab a wad of paper towels with a pair of long-handled tongs and dip them in a bowl of vegetable oil. When the towels have absorbed the oil, run them over the cleaned grill grate. The oil will burn off at first. Continue to dip the towels into oil and slick down the grate; it will become “nonstick.” When the grate turns black and glossy, your grill is good to go.
Put the burgers on the grill.
Flip the burgers just once—after they’ve developed deep brown grill marks—and don’t be tempted to press on them. Pressing down on the burgers as they cook squeezes out the flavorful juices, which end up in your grill (causing flare-ups) instead of in your burgers.
Take the temperature in the center of each burger with an instant-read thermometer.
