To get the Bratwurst to a nice, dark brown color, brush them with beer before grilling or frying. Alternatively, sprinkle the Bratwurst with a little sugar. The sugar caramelizes, giving the Bratwurst a rich brown color. To prevent the Bratwurst skin from splitting, heat them in hot (not boiling) water for 5 minutes. Dry them, then sprinkle them with flour. Fry them in a frying pan with a little oil or butter. For a different flavor, add fresh sage, rosemary, or oregano to the frying pan and brown the Bratwurst with the herbs.
