Sure, you can simply cook brats on the grill from start to finish, but for more evenly cooked meat, poach the links in a bath of simmering beer and chopped onions first. Once the brats are cooked through, sear them on a hot grill for some char.
Concerning the bun, there is no debate—a Martin's Potato Roll is the only suitable vessel for a brat.
Top It Off
When it comes to toppings, it's best to keep things simple. The perfect combo is classic yellow mustard and sauerkraut.
