Gil-gamja are one of those Korean street foods that make you question why regular french fries even exist. (Just playing!) The outside is golden and crispy. The inside is stretchy and chewy, almost like mochi. The secret is tapioca starch mixed into a real potato base, which gives them that addictive pull that keeps you reaching for one more.
These went viral on TikTok for a reason. They look impressive, they taste incredible, and they take about 30 minutes from start to finish. No special equipment needed beyond a blender and a piping bag.
The sriracha-mayo dipping sauce is optional but strongly recommended. The sweetness from the plum syrup balances the heat perfectly.
Ingredients
- 400g peeled potato
- 130g water
- ½ tsp salt
- 100g tapioca starch
- Neutral oil for deep frying
Dipping sauce:
- 2 tbsp mayonnaise (30g)
- 1 tbsp sriracha (15g)
- 1 tbsp plum syrup (20g)
Singapore Swap
- Tapioca starch: Available at FairPrice, Sheng Siong, or any baking supply shop.
- Plum syrup (maesil-cheong): Korean grocery stores or Don Don Donki. If unavailable, substitute with honey and a squeeze of lemon.
- Sriracha: Huy Fong (rooster bottle) from any supermarket.
Instructions
1. Blend the potatoes
Combine peeled potatoes and water in a blender. Blend until completely smooth with no lumps.
2. Microwave and stir
Pour the mixture into a microwave-safe bowl. Microwave for 5 minutes total, but stop every 30 seconds to stir thoroughly. This constant stirring is what creates the chewy texture. Do not skip this step.
3. Add starch and form the dough
Transfer the thickened potato paste to a mixing bowl. Add salt and tapioca starch. Mix until it forms a thick, stretchy dough.
4. Pipe into oil
Scoop the dough into a piping bag. Heat neutral oil in a deep pan to around 170-180°C. Pipe the dough directly into the hot oil in short strips, about 8-10cm each.
5. Fry until golden
Fry until each piece turns golden brown. This takes about 3-4 minutes per batch. Remove and drain on paper towels.
6. Make the dipping sauce
Mix mayonnaise, sriracha, and plum syrup until smooth. Adjust the sriracha to your heat preference.
Tips
- The stirring every 30 seconds is non-negotiable. It creates the chewiness. Skip it and you get regular mashed potato.
- If you do not have a piping bag, cut the corner off a ziplock bag. Works the same way.
- These are best eaten immediately. The crispiness fades after 15-20 minutes.
- Oil temperature matters. Too hot and they burn outside while staying raw inside. Too cool and they absorb oil and get greasy.
