Rub the meat with the salt and pepper. Poke the tip of a small, sharp knife into the meat and insert the pieces of garlic. Alternatively you can rub the meat with a spice rub of your choice.
Put it on the grill over red oak coals, fat side up, and sear for about 5 minutes. Turn it over and adjust the grate so that the meat is about 8 inches from the coals. Cook the meat for approximately 20 minutes per inch of thickness or until it reaches an internal temperature of 130°. Remember Encarnación’s advice to “watch it continuously, turning the meats so they stay moist yet get well browned.”
Remove and let rest for a few minutes. You can trim the fat then slice against the grain and serve with fresh tomato salsa.
