This recipe guides you through preparing grilled bratwurst by first simmering them in a flavorful mixture of lager beer, whole grain mustard, and sauerkraut, optionally with thyme. The sausages are then finished on a hot grill to achieve a perfect char, and served in buns with the warm, savory sauerkraut and extra mustard.
Achieve optimal flavor by using a good quality, full-flavored lager for simmering; avoid light beers. Do not pierce the bratwurst before simmering, as this prevents them from bursting and losing precious juices and flavor. The simmering liquid should be gently bubbling, not rapidly boiling, to ensure even cooking without toughening the sausages. When grilling, aim for a deep golden-brown char, which adds a crucial smoky dimension and texture. Toasting your buns lightly on the grill while the bratwurst rests will elevate the final presentation and eating experience.
