Twice-Cooked French Fries

Bring large pot of salted water to boil. Line large baking sheet with several layers of paper towels.

Cut 1 potato lengthwise into 1/4-inch-thick slices. Stack 2 to 3 potato slices at a time and cut lengthwise into 1/4-inch-wide sticks. Cook potato sticks in boiling water just until beginning to soften, 3 to 4 minutes. Using slotted spoon or tongs, transfer potato sticks to paper-towel-lined baking sheet to drain. Repeat cutting, blanching, and draining remaining potatoes. Pat potato sticks dry with additional paper towels. DO AHEAD: Can be made 4 hours ahead.

Let stand uncovered at room temperature.

Pour enough canola oil into heavy large pot to reach depth of 4 inches. Attach deep-fry thermometer to side of pot; heat oil to 350°F. Working in batches, add potato sticks to oil and fry until golden brown, about 6 minutes.

Transfer to clean paper towels to drain.

Sprinkle with salt and pepper.

Serve immediately.

For best results, serve each batch of fries immediately. If necessary, they can be kept warm on a rimmed baking sheet in a 300°F oven while the remaining potatoes are fried.
