Ingredients

Instructions

  1. Step 1: Peel and slice 1 large sweet onion into 1/2-inch thick rings, separating them carefully into individual rings.
  2. Step 2: In a large bowl, whisk together 1 1/2 cups all-purpose flour, 1/4 cup cornstarch, 1 tsp baking powder, 1 tsp paprika, 1/2 tsp cayenne pepper, 1 tsp salt, and 1/2 tsp black pepper.
  3. Step 3: Gradually whisk in 1 cup cold sparkling water to the dry ingredients until smooth and thick enough to coat the onion rings.
  4. Step 4: Heat 4 cups vegetable oil in a deep pot or fryer to 375°F. Dip each onion ring into the batter, letting excess drip off, then carefully place into hot oil.
  5. Step 5: Fry onion rings in batches for 2-3 minutes until golden brown and crispy, turning once. Remove with a slotted spoon and drain on paper towels before serving.
