Ingredients:
2 quarts vegetable oil, for frying
3 cups flour ( cake flour is best)
1 cup cornstarch
2 teaspoons baking soda
2 teaspoons salt, plus more for sprinkling ( use kosher if possible)
2 1/2-3 cups chilled club soda
2 large Spanish onions, cut into 1/2-inch slices and separated into rings
Directions:
In a very large pot (or deep fryer), heat the oil to 365F.
In a bowl, whisk the flour with the cornstarch, baking soda and 2 teaspoons of salt.
Add 2 1/2 cups of the club soda and whisk until smooth; the batter should be thick but pourable. If needed, add the remaining 1/2 cup of club soda, a few tablespoons at a time.
Working with 6 or 7 onion rings at a time, dip them in the batter until completely coated; as you pull the rings from the batter, scrape some of the excess against the side of the bowl.
Carefully add the onion rings to the hot oil and fry until golden and crisp, about 2 minutes.
Drain the onion rings on paper towels.
Sprinkle the onion rings with salt and serve immediately or keep warm in an oven on low heat while you coat and fry the rest. Enjoy!
