# Step-by-Step Instructions:
01 - Peel onions and slice into ¾-inch thick rings. Separate rings and set 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 eggs with cold sparkling water until well blended.
04 - Add wet mixture to dry ingredients and whisk until smooth. If batter is too thick, add a splash more sparkling water.
05 - Place panko breadcrumbs in a shallow dish for coating.
06 - Dip each onion ring into the batter, allowing excess to drip off, then coat thoroughly in panko breadcrumbs.
07 - Heat vegetable oil to 350°F in a deep fryer or heavy pot. Fry onion rings in batches for 2–3 minutes, turning occasionally, until golden and crispy. Drain on wire rack or paper towels.
08 - Preheat air fryer to 400°F. Arrange coated rings in a single layer, spray lightly with oil, and air-fry for 8–10 minutes, turning halfway until crisp and golden.
09 - Stack fried rings into a tower on a serving platter and serve immediately with preferred dipping sauces.
