Bratwursts With Caramelized Onions & Creamy Horseradish

This recipe is from Gail Ciampa of the Providence Journal. I've been making it for 2 years and its a family favorite. The taste sensation of biting through the cold horseradish sauce, the warm caramelized onions, the crisp garlicky brat and the toasted roll is pure heaven.

• Ready In: 1 hr
• Serves: 6

Ingredients

• bratwursts on toasted rolls with caramelized onions and horseradish sauce

• 3  tablespoons unsalted butter
• 1  lb yellow onion, thinly sliced
• 1⁄2 teaspoon sugar
• 6  bratwursts
• 6  good quality  hot dog buns, lightly toasted

• creamy horseradish sauce

• 1  cup sour cream
• 1⁄4 cup  minced unpeeled granny smith apples or 1⁄4 cup  other tart apple
• 2  tablespoons  prepared horseradish
• 1  teaspoon caraway seed

Directions

1. To caramelize onions, heat butter in a large, heavy skillet over medium-high heat. When melted and hot, add onion slices and cook until golden brown, stirring occasionally, 10-15 minutes.
2. Add sugar and cook until onions are deep golden brown, stirring frequently, about 5 minutes more.
3. Remove onions from heat and set aside.
4. Mix all horseradish sauce ingredients together in a small bowl and refrigerate until ready to use.
5. Grill brats (I prefer to slice them partially through).
6. Place in toasted buns, spread with (mustard) onions and then horseradish sauce.
