Pour oil into medium-size pot to depth of 5 to 6 inches. Heat to 325°F on deep-fat frying thermometer.
With slotted metal spoon, add 10 potato sticks at a time to oil; fry 2 minutes, until very lightly colored. Remove with spoon to pan. (Let oil return to 325°F before adding more sticks.)
Heat oil to 375°F. Working in 2 or 3 batches, add sticks to oil; fry 1-1/2 to 2 minutes, until golden brown and cooked through. With spoon, transfer to toweling to drain. Sprinkle with salt.
