Double-Fried Potato Chips

There are two things to love about these double-fried potato chips: their uncompromising crunch and how reliably they come out the same every time. Using high-starch Russets and a two-step cook—first a low-temperature blanch to gently cook the flesh, then a high-temperature flash to evaporate remaining moisture—delivers that glassy, shattering crisp that single-stage frying rarely achieves. The ice bath with a touch of vinegar pulls surface starch, keeps slices from oxidizing, and helps the slices stay translucent rather than mottled; the optional cornstarch is a surgeon’s trick for an extra-thin, brittle shell without adding bulk. The result is a chip that snaps cleanly and carries seasoning beautifully, whether you keep it salt-and-paprika simple or finish with a fine-grain flavored salt.

This recipe lives at parties, on sandwich plates, or in a bowl for afternoon grazing, and it’s built to be forgiving so a determined home cook can get professional results. You don’t need a fryer—just a heavy pot and a reliable thermometer—and the method scales: work in small batches, let the first-fry pieces cool, then blitz them hot for the final crackle. If you care about texture more than speed, this technique rewards patience with a chip that tastes like it came from a specialty shop.
