Sieve through your flour into a large bowl. Add the salt, white sugar, yeast, and milk

Mix the mixture well, until it becomes a dough. Cover the bowl with plastic wrap

Ferment bowl at room temperature until dough doubles in size. Once the dough is finished growing in size, punch your dough a few times to release gas. Cover bowl with the wrap again and sit out for 20 minutes

After the 20 minutes is completed, place some oil on your hands and separate dough into 6 pieces

Take a piece and flatten your dough and place 1 tablespoon of filling onto the dough. Once done, seal each dough by gathering each corner. Repeat with the remaining pieces

Preheat a frying pan on medium heat

Once the pan is finished heating, add a thin layer of oil

Keep the heat at medium and place 1 dough piece onto the pan and cook each side until lightly golden brown, which usually takes 30 seconds

Flip the piece over and press with a hotteok press (a solid turner spatula would work too) until bottom side is golden brown, which usually takes 1 minute to complete. Flip again and reduce heat to low. Cover the pan with a lid and cook for 1 minute. Place hotteok onto place once done cooking

Repeat steps 8 and 9 with the remaining pieces.

Enjoy!
