Best. Brats. Ever

Found a recipe for cooking brats on the grill at firecooker dot com. Starts by softening onions and garlic in a pan while lightly browning the brats on the grate. Once the onions are soft, add a dark beer and the partially cooked brats. Cover and let them swim in the beer and onion flavored pool for 20 minutes. Uncover and let the beer reduce down.
I also found that the 20 minute window is perfect for cooking some burgers on the already hot grill.
