Vegetable oil, for frying
1 cup all-purpose flour
2 tablespoons cornstarch
1/2 teaspoon baking powder
1/2 teaspoon kosher salt
1 teaspoon Old Bay Seasoning, plus more for sprinkling
1 cup plus 2 tablespoons chilled club soda
1/2 pound green beans
In a large, deep skillet, heat 1/2 inch of oil until shimmering. In a large bowl, whisk the flour with the cornstarch, baking powder, salt and the 1 teaspoon of Old Bay. Gently whisk in the club soda until the batter just comes together.
Working in batches, dip the green beans in the batter, let the excess drip off and add them to the hot oil. Do not overcrowd the pan or they will stick to each other. Fry until light golden and crisp, 2 to 3 minutes. Using a slotted spoon, transfer to a paper towel–lined baking sheet to drain. Season and serve! Goes GREAT with Ranch or Honey-Mustard dressing!
