Beer-Braised Bratwursts With Onion - cooking recipe

Ingredients

2 teaspoons mustard seeds (black or brown)
1 teaspoon caraway seed
1 tablespoon unsalted butter
12 bratwursts
2 medium white onions, sliced into 1/4-inch-thick rings
1 1/2 cups brown ale, such as Newcastle
12 hoagie rolls
1 cup sweet-hot mustard
2 tablespoons sweet-hot mustard

Preparation

Place mustard seeds and caraway seeds in a small resealable plastic bag and crush with a meat mallet or rolling pin.
Melt butter in a Dutch oven or a large, heavy-bottomed pot with a tightfitting lid over medium heat. When the foaming subsides, add 6 of the bratwursts and cook, turning, until browned on all sides, about 10 minutes. Remove to a plate and repeat with remaining bratwursts.
Reduce heat to low, add crushed seed mixture and onions, and season generously with salt and freshly ground black pepper. Cook, stirring occasionally, until onions have softened and are beginning to brown, about 30 minutes. Add reserved bratwursts and any accumulated juices, nestling the brats in the onions. Pour in beer and braise bratwursts, turning once, until they are completely cooked through, about 30 minutes. Season with salt and pepper to taste.
Toast hoagie rolls and spread about 1 1/2 tablespoons mustard on each. Place a bratwurst in each bun and cover with onions.
