Step 1

Fill a small Dutch oven with 3 to 4 inches of oil and heat over medium heat until a deep-frying thermometer inserted in the oil registers 325 degrees F. Line a large plate or baking sheet with paper towels.

Step 2

In a medium bowl, whisk together the flour, cornstarch, paprika, baking powder, garlic powder, onion powder, cayenne, 2 teaspoons salt and 1/2 teaspoon black pepper. Add 1 cup of the beer and stir until smooth, adding more beer a tablespoon at a time if necessary until the batter is the consistency of heavy cream. Set aside.

Step 3

Using kitchen towels, dry the potatoes thoroughly. Working in batches, slide the potatoes into the oil, being careful not to crowd the pan, and cook until lightly golden, about 5 minutes. Use a slotted spoon or skimmer to remove to the towel-lined plate and sprinkle with a few pinches of salt.

Step 4

Raise the oil temperature to 350 degrees F. Dip the partially cooked fries a few at a time in the batter to coat. Using a fork, slide the coated potatoes 1 at a time into the oil, about 6 or 8 in a batch so as not to overcrowd the pan. Use a metal skimmer or tongs to keep them separate, as they tend to cling together. Cook until deep golden brown, 2 to 3 minutes. Remove to fresh paper towels to drain. Serve immediately.
