Method

Preparing the Onion Rings

  1. 1

    Slice the Onions

    Peel the onions and slice them into thick rings, about 1/2 inch wide. Carefully separate the rings and set aside.

  2. 2

    Prepare the Batter

    In a large bowl, mix together the all-purpose flour, cornstarch, baking powder, salt, black pepper, and chili powder. Gradually whisk in the cold sparkling water until you achieve a smooth batter.

  3. 3

    Heat the Oil

    In a deep pot or fryer, heat the vegetable oil to 375°F (190°C).

  4. 4

    Coat the Onion Rings

    Dip each onion ring into the batter, allowing excess batter to drip off.

  5. 5

    Fry the Onion Rings

    Carefully place the battered onion rings into the hot oil in batches. Fry until golden brown and crispy, about 2-3 minutes per side. Remove and drain on paper towels.

Making the Ranch Dressing

  1. 6

    Combine Ingredients

    In a medium bowl, combine the mayonnaise, sour cream, buttermilk, dried dill weed, garlic powder, onion powder, salt, and black pepper.

  2. 7

    Mix Well

    Mix all the ingredients together until smooth and creamy. Adjust seasoning to taste.

  3. 8

    Chill the Dressing

    Cover the ranch dressing and refrigerate for at least 30 minutes before serving to let the flavors meld.
