Saw a version of this on Diners, Drive-Ins and Dives, so had to give it a shot at home. Start with a 1/3# hamburger, season as you like. Smoke for about 30 minutes. While smoking, heat up a frying pan on medium-high heat. Fry the burger on one side. After flipping, sprinkle 1/3# of shredded cheddar over burger, allowing to generously flow over the sides. Cover skillet and let cook about 1 minute. Burger will be done and cheese will be nicely toasted. My cheesy daughters thought this was the best burger ever!
