Prepare the Potatoes:
Peel the potatoes and cut them into sticks of your preferred size.
Soak the potato sticks in a bowl of cold water for at least 30 minutes or up to several hours. This step removes excess starch, which helps in getting them crispier.
Coat with Cornstarch:
Drain the potatoes and pat them dry with paper towels.
Sprinkle the cornstarch over the potato sticks and toss them until they are evenly coated.
Fry the Potatoes:
