Ingredients

  • 2 large potatoes (Russet or Yukon Gold)
  • 1/4 cup cornstarch
  • 1/4 cup all-purpose flour
  • 1/2 tsp salt
  • 2–4 tbsp water (as needed)
  • Vegetable oil, for frying
  • Optional seasonings: garlic powder, paprika, nori flakes, black pepper, chili powder

Instructions

  1. Peel and boil potatoes until soft, about 10–12 minutes.
  2. Drain and mash potatoes until smooth and lump-free.
  3. Add cornstarch, flour, salt, and water to form a thick dough.
  4. Transfer the dough to a piping bag with a large round tip or a plastic bag with a corner cut off.
  5. Heat vegetable oil in a deep pan to 350°F (175°C).
  6. Pipe long strips of dough into the oil, cutting with scissors to desired length.
  7. Fry for 2–3 minutes per batch, until golden and crispy.
  8. Remove with a slotted spoon and drain on paper towels or a wire rack.
  9. Season immediately and serve hot.

Notes

  • For extra crispness, add potato starch or grated cheese to the dough.
  • Use sweet potatoes for a naturally sweeter version.
  • To bake instead of fry, pipe onto parchment and bake at 425°F (220°C) for 20 minutes.
  • Reheat in an air fryer or oven to restore crispness.
  • Dust with cinnamon sugar for a sweet version.
