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)

Directions

Step 1

Peel the onions and cut them into 1/2-inch thick slices. Separate them into individual rings and set aside.

Step 2

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.

Step 3

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.

Step 4

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.

Step 5

Dip each onion ring into the tempura batter, ensuring it is evenly coated. Allow any excess batter to drip off.

Step 6

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.

Step 7

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.

Step 8

Serve the tempura onion rings immediately with your favorite dipping sauce, such as aioli, ketchup, or soy-based sauce.
