Cut the potatoes into sticks about 3 to 4 inches long and 1/2 inch thick.

As you work, put the cut potatoes in a large bowl of cold water to keep them from discoloring from contact with the air.

When you’re finished, drain and rinse the potatoes, then cover with fresh cold water, a couple handfuls of ice cubes, and the lemon juice. Refrigerate for 2 - 3 minutes.

Using the spider or tongs, transfer the fries to fresh sheets cut from a clean brown paper bag, or paper towels, to drain briefly. Sprinkle with salt and serve immediately, with or without ketchup.
