Batter

Onion Rings

Method

Prepare the Batter

  1. 1

    Mix Dry Ingredients

    In a large mixing bowl, combine the all-purpose flour, cornstarch, baking powder, garlic powder, onion powder, salt, and black pepper. Whisk together until well combined.

  2. 2

    Add Sparkling Water

    Gradually add the cold sparkling water to the dry mixture, stirring gently until the batter is smooth and free of lumps. Do not overmix; a few small lumps are acceptable. Set aside for about 15 minutes.

Prepare the Onion Rings

  1. 3

    Slice the Onions

    Peel the large onions and slice them into 1/4 inch thick rings. Carefully separate the rings and place them in a bowl.

  2. 4

    Heat the Oil

    In a deep frying pan or pot, heat the vegetable oil over medium-high heat until it reaches 350°F (175°C). You can test if the oil is ready by dipping a small amount of batter into it; if it sizzles and bubbles, the oil is hot enough.

Fry the Onion Rings

  1. 5

    Coat the Onion Rings

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

  2. 6

    Fry the Onion Rings

    Carefully place the coated onion rings into the hot oil, a few at a time, taking care not to overcrowd the pan. Fry for about 3-4 minutes or until golden brown and crispy, turning occasionally for even cooking.

  3. 7

    Drain and Serve

    Once cooked, use a slotted spoon to remove the onion rings from the oil and place them on a plate lined with paper towels to drain excess oil. Serve hot with your favorite dipping sauce.
