Bratwurst seared until deeply browned, then braised in lager, mustard, and caraway until the liquid reduces into a glossy pan sauce.
Use lager or pilsner, not a hoppy IPA — bitterness concentrates as the beer reduces. Don"t rush the braise: the sauce needs to reduce until it coats a spoon or the dish will taste watery. Stir in the mustard off heat so it keeps its texture. Serve over soft pretzel buns, mashed potatoes, or spaetzle to catch the sauce.
