Wash your potatoes and cut the potatoes into thin slices using a mandoline.
Soak the potato slices in a large bowl of ice water for ½ hour to remove excess starch.
Dry off the potato slices.
Fry the potato slices in small batches in your deep fryer set at 350 degrees, until they are golden brown. Cook in small batches so that the oil doesn't cool down too much.
Drain them on a paper towel lined baking sheet, and add the salt and pepper right away, if you wait too long it won’t stick. They may not be crispy when you first take them out of the fryer, they need a few minutes to crisp up.
