# Ingredient List:

02 - 1 cup all-purpose flour
03 - ½ cup cornstarch
04 - 1 teaspoon baking powder
05 - 1 teaspoon smoked paprika
06 - 1 teaspoon garlic powder
07 - 1 teaspoon salt
08 - ½ teaspoon freshly ground black pepper

10 - 2 large eggs

11 - 2 cups panko breadcrumbs

# How to Make:
01 - Peel the onions and slice them into ¾-inch thick rings. Separate the rings and set them aside.
02 - In a large bowl, whisk together flour, cornstarch, baking powder, smoked paprika, garlic powder, salt, and black pepper.
03 - In a separate bowl, beat the eggs and sparkling water until well blended.
04 - Pour the wet ingredients into the dry mixture and whisk until smooth. If the batter is too thick, add a little more sparkling water.
05 - Spread the panko breadcrumbs evenly in a shallow dish.
06 - Dip each onion ring into the batter, letting excess drip off, then coat thoroughly with panko breadcrumbs.
07 - Heat vegetable oil to 350°F (175°C) in a deep fryer or heavy pot. Fry onion rings in batches for 2 to 3 minutes, turning occasionally, until golden and crisp. Drain on a wire rack or paper towels.
08 - Preheat the air fryer to 400°F (200°C). Arrange coated rings in a single layer, spray lightly with oil, and air-fry for 8 to 10 minutes, flipping halfway through until golden and crisp.
09 - Stack the cooked onion rings into a tower on a serving platter and serve immediately with favorite dipping sauces.
