Recipe Information
Ingredients
- 2 pieces Large onions
- 150 grams All-purpose flour
- 50 grams Cornstarch
- 1 teaspoon Baking powder
- 200 milliliters Ice-cold sparkling water
- 1 liter Vegetable oil (for frying)
- 1 teaspoon Salt
- 0.5 teaspoon Black pepper (optional)
Instructions
Peel the onions and cut them into 1/2-inch thick slices. Separate them into individual rings and set aside.
In a mixing bowl, combine the all-purpose flour, cornstarch, baking powder, salt, and black pepper (if using). Stir the dry ingredients until well mixed.
Gradually add the ice-cold sparkling water to the dry ingredients, whisking gently until a smooth batter forms. Be careful not to overmix; the batter should remain slightly lumpy.
In a deep pot, heat the vegetable oil over medium-high heat until it reaches 350°F (180°C). Use a kitchen thermometer to monitor the oil temperature for consistent frying results.
Dip each onion ring into the tempura batter, ensuring it is evenly coated. Allow any excess batter to drip off.
Carefully lower the coated onion rings into the hot oil, a few at a time, to avoid overcrowding. Fry for 2-3 minutes or until golden and crispy, flipping halfway through for even browning.
Use a slotted spoon to remove the fried onion rings from the oil and transfer them to a plate lined with paper towels to drain excess oil.
Serve the tempura onion rings immediately with your favorite dipping sauce, such as aioli, ketchup, or soy-based sauce.
