  • 1.5 teaspoons (9g) Fine Sea Salt Divided use
  • 1.5 cups (355ml) Club Soda Must be ice-cold
  • 1 quart (946ml) Neutral Oil Canola or Peanut oil

Method
 

Preparation
  1. Peel and slice onions into 1/2-inch rings. Separate rings and remove the inner thin membrane.
  2. Toss the onion rings in 1/2 cup of flour and 1/2 tsp salt until fully coated.
Frying
  1. Heat oil in a heavy pot to 375°F (190°C).
  2. Whisk remaining flour, cornstarch, baking powder, salt, and cold club soda. Dip rings into batter and fry in batches for 2-3 minutes until golden brown.
  3. Transfer to a wire rack and immediately sprinkle with flaky sea salt while still glistening.

Notes

Use ice-cold liquid for the batter to ensure maximum crunch.
Maintain oil temp at 375°F to prevent the rings from becoming greasy.
