Step 1

Heat the oil to 375 degrees F in a heavy-bottomed Dutch oven or deep fryer. Preheat the oven to 200 degrees F.

Step 2

Mix the salt, garlic powder, paprika and sugar in a bowl and set aside.

Step 3

Whisk the cornstarch and club soda in a mixing bowl. In batches, dip the potatoes in the batter, allow any excess to drip off and hold on a wire rack. Repeat with rest of the potatoes.

Step 4

Fry half the potatoes, stirring occasionally until golden brown and crispy, 6 to 8 minutes. Sprinkle with the seasoning and hold in the oven on a paper towel-lined baking sheet. Repeat with the last batch of potatoes.
