From a kiosk in Lotte Mart. A whole cleaned potato was put through a machine to make it into one long spiral, then poked through a skewer to expand it. It was then bathed with a thin batter and deep-fried for around 10 minutes, then drained and coated with a seasoning of your choice - onion, cheese or BBQ. Although the cheese is more popular, it tastes a bit funny. Onion is recommended. My little girl loves it to bits but it's quite oily, so can't have it too often!
