1. Cut the potatoes into wedges and throw them in a bowl.
2. Wash the cut potatoes thoroughly under running water, agitating them with your hand until the water runs clear.
3. Thoroughly dry the potatoes with a paper towel or clean kitchen towel.
4. In a large bowl, toss the dried potatoes with flour and all-purpose seasoning until evenly coated.
5. Let the potatoes sit for 2-3 minutes to allow the breading to build up.
6. Toss the potatoes again as needed, to ensure even coating.
7. Heat vegetable oil in a pot to 350°F.
8. Add breaded potatoes to the hot oil and cook for about 8 minutes, or until the potatoes feel like you're moving around rocks in the pan, indicating they are perfectly crispy.
