Bratwursts on Toasted Rolls with Caramelized Onions and Creamy Horseradish Sauce
3 tablespoons unsalted butter
1 pound yellow onions, thinly sliced
1/2 teaspoon sugar
6 good quality hot dog buns, lightly toasted
Creamy Horseradish Sauce (recipe follows)
1 cup sour cream
1/4 cup minced unpeeled Granny Smith or other tart apple
2 tablespoons prepared horseradish
1 teaspoon caraway seeds
Mix all ingredients together in a small bowl and refrigerate until ready to use.
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. Add sugar and cook until onions are deep golden brown, stirring frequently, about 5 minutes more. Remove onions from heat and set aside.
Creamy Horseradish Sauce; Mix all ingredients together in a small bowl and refrigerate until ready to use.
Grill brats (I prefer to slice them partially through). Place in toasted buns, spread with onions and then horseradish sauce.
