In a small bowl, combine warm milk, instant yeast, and sugar. Set aside for 5 minutes.

In a separate large bowl, combine all dry ingredients. Pour the milk and yeast mixture into the dry ingredients bowl.

Stir until a smooth dough forms. Cover the dough; let it rest for at least one and a half hours, or until it has tripled in size.

Heat vegetable oil in a large saucepan over medium heat. (You can begin preparing the dough while the oil is heating.)

Lightly grease your hands. Grab a handful of dough, flatten it out in your palm. Place 2 tablespoons of cheese into the center of the dough. Fold the edges together, around the cheese, and seal the dough at the edges. Repeat with remaining dough.

Add the uncooked hotteok to the hot pan and gently flatten it. Cook for approximately 1 minute, or until golden brown. Flip the hotteok and gently press down again to flatten a bit more. Cook for another minute, or until it’s golden brown on both sides.

Set aside the cooked hotteok on paper towels to absorb any excess oil. Serve hot, enjoy!
