Peel and rinse the potatoes. Cut into 3/8 inch lengths. Wipe them dry. Heat the oil to 375 F, and fry the potatoes in batches until cooked but still white, for 12 to 15 minutes. Turn off the heat. 20 minutes before serving, heat the oil again. Cook the French fries until golden. Place them on a serving platter. Sprinkle with salt.
