Answer Wiki. First off, one does NOT boil bratwurst. One gently simmers bratwurst in a lager or pilsner beer with plenty of julienned yellow onions for about 10-15 minutes. The brats are then grilled over charcoal until uniformly brown, put in brat buns along with some of the onions and some good brown mustard.
Let simmer over medium heat, occasionally stirring; bring to a gentle boil and reduce heat to low. Simmer another 5 minutes, then add paprika and curry to taste. Simmer 1 min more and taste, adding more curry powder if needed.. 3. Meanwhile, broil/grill knockwurst sausage for 3 to 4 minutes each side, or until cooked through.
