Ingredients

• 240 ml lukewarm water
• 1 tbsp white sugar
• 2 tsp instant dry yeast
• ½ tsp salt
• 1 tbsp neutral vegetable oil
• 220 g all-purpose flour
• 60 g glutinous rice flour (chapssal-garu)
• 100 g dark brown sugar
• 1 tsp ground cinnamon
• 30 g walnuts
• 4 tbsp neutral vegetable oil

Method

1. 01
   Wake the yeast Pour the lukewarm water into a large bowl, stir in the white sugar and the yeast, and leave it for about five minutes until it looks a little foamy.
2. 02
   Mix the dough Add the salt, one tablespoon of oil, the all-purpose flour and the glutinous rice flour, and stir with a wooden spoon for about two minutes until you have a smooth, very sticky dough.
3. 03
   Let it rise Cover the bowl with a damp cloth or plastic wrap and leave it in a warm spot for about one hour, until the dough has doubled in size.
4. 04
   Make the filling While the dough rises, mix the brown sugar, cinnamon and chopped walnuts together in a small bowl.
5. 05
   Knock back and rest Punch the dough down with your fist to release the air, cover it again, and let it rest for fifteen minutes.
6. 06
   Fill the pancakes Oil your hands, take an eighth of the dough, flatten it in your palm, put about one and a half tablespoons of filling in the middle, and pinch the edges together to seal it into a ball. Repeat to make eight.
7. 07
   Heat the pan Heat a large frying pan over medium heat with about one tablespoon of oil for one minute.
8. 08
   Fry the seam side Place two or three dough balls in the pan seam side down and fry for about one minute until the bottom is golden.
9. 09
   Flip and press Turn each ball over and press it flat with an oiled spatula or a hotteok press until it is about ten centimetres wide, then fry for one more minute.
10. 10
    Finish covered Flip the pancakes again, turn the heat to low, cover the pan, and cook for two minutes so the sugar inside melts into syrup.
11. 11
    Repeat and serve Move the cooked hotteok to a plate, add a little more oil to the pan, and fry the rest the same way. Serve them warm.
