One medium vidalia onion rough chopped, sauteed with 4 tbsp of Kerrygold butter, 1/2 tsp kosher salt and equal amount of fresh black pepper. Beer added along with brats and 1/2 tsp caraway seeds. Sauerkraut was added and allowed to simmer for another 15 minutes. These were really good.... Cauliflower tots and garden peppers for sides.
