Start by combining the beef, egg, evaporated milk, Worcestershire and rub in a bowl. Use your hands to mix well. Divide this mixture into 4 equal parts. Then take each of the 4 parts and divide them in half. Take each of these smaller parts and flatten. The goal is to have 8 equal flat patties that you will then combine into 4 hamburgers. Once you have your patties flattened, place your cheese (or whatever you want to stuff the burgers with, just don’t overload the burgers to prevent a massive blow-out on the grill) in the middle and then place the other patty over this and tightly pinch the sides to seal. You may even want to push the meat back towards the center a bit to form a slightly thicker patty. The patties should be slightly larger than a standard hamburger bun as they will shrink a little during cooking.

Preheat your Kong to 300 degrees.

Keep in mind during grilling that you basically have two thin patties, one on each side, so the cooking time should not be long. You will cook these for 5 to 8 minutes per side—closer to 5 minutes if you prefer a rare burger or more towards 8 minutes if you like a well-done burger.

When you flip the burgers, take a toothpick and pierce the center of the burger to allow steam to escape. This will keep you from having a blow-out or having a guest who gets a chin burn from molten cheese as they take their first bite.

Throw these on a nice roll and top with ingredients that complement whatever your burgers are stuffed with.
