1. Wash and peel your potatoes, then cut them into your desired fry shape.
2. In a large pan or deep fryer, part fry the potatoes for about 2 minutes on high heat.
3. Remove the partially fried potatoes and place them in the freezer for about 1 hour.
4. While the potatoes are in the freezer, prepare the batter: In a bowl, combine the all-purpose flour, cayenne pepper, paprika, onion powder, garlic powder, mustard powder, and pepper. Mix well.
5. Gradually add club soda to the dry mixture, stirring until you have a smooth batter of desired consistency.
6. After 1 hour, take the fries out of the freezer and dunk them into the prepared batter, ensuring they are fully coated.
7. Return the battered fries to the hot oil and fry them off until they are golden brown and crispy.
8. Remove from oil, salt them lightly to taste, and enjoy immediately.
