- Vegetable oil, for frying
- 1/2 cup buttermilk
- 1 egg
- 1 teaspoon hot sauce
- 1 cup all-purpose flour
- 1 teaspoon cayenne pepper
- 1/2 teaspoon freshly ground black pepper
- 2 Vidalia onions, sliced into 1/2-inch thick strips
Place oil in a deep skillet until it comes about 1-inch up the side of the pan. Heat oil to 360 degrees F.
Mix buttermilk, egg, and hot sauce in a medium bowl. Mix flour, cayenne, 1 teaspoon salt, and pepper in a bag. Pat onion slices dry and dip in the buttermilk mixture to coat. Transfer slices to bag and toss to coat. Deep-fry onions in batches until golden, about 2 minutes. Transfer to a paper towel-lined plate to drain, sprinkle immediately with salt, and serve.
