6 to 10 potatoes
3 cups vegetable oil
Salt, to taste
Wash potatoes. Keep the peel on. Slice them very thin with a slicer or by hand. Put potato slices in ice water for about 10 minutes, then drain very well.
Meanwhile, heat oil in a pan. Drop the potatoes carefully so the oil doesn't splatter, and deep fry them until they are crispy. Drain and add salt to taste.
