Ingredients

  • 3 medium russet potatoes peeled and cut into chunks
  • ¾ cup cornstarch about 100 grams
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon paprika
  • ½ teaspoon black pepper
  • ½ teaspoon cayenne pepper optional, for heat
  • Salt to taste (plus extra for finishing)
  • Neutral oil for frying vegetable oil, canola oil, or peanut oil

Instructions

  • Boil peeled and chopped russet potatoes in well-salted water for 15–20 minutes until completely fork-tender, then drain and steam-dry for 2–3 minutes.
  • Mash the potatoes thoroughly until completely smooth with no lumps remaining.
  • Add cornstarch and all spices to the warm mashed potatoes and mix firmly until a smooth, cohesive dough forms.
  • Place the dough between two large sheets of parchment paper and roll out evenly to approximately ¼ inch thickness using a rolling pin.
  • Transfer the parchment-wrapped sheet to the refrigerator and chill for a minimum of 30 minutes until firm.
  • Remove from refrigerator, peel back the top parchment sheet, and cut into long thin strips using a sharp knife or pizza cutter.
  • Heat neutral frying oil in a deep skillet or Dutch oven to 350°F–375°F.
  • Fry strips in small batches for 3–5 minutes, turning occasionally, until deeply golden brown all over — do not overcrowd the pan.
  • Remove with a slotted spoon onto a wire rack or paper towel-lined plate.
  • Season immediately with a pinch of salt while still hot and serve right away.
