Measurements · 1 tbsp = 15 ml (a heaping regular dinner spoon) · 1 tsp = 5 ml (a heaping teaspoon) · 1 cup = 200 ml (a Korean measuring cup or small paper cup, not the 240 ml US cup)
  • Sift the flour twice.
  • Warm the water beforehand.
  • Adding almond or peanut powder to the filling makes it even nuttier.

Steps

  1. Place the sugar, salt, and yeast on top of the sifted flour, keeping them spaced apart.

    Mix the salt and sugar into the nearby flour with a spatula.

    Mix the yeast with the flour surrounding it as well.

    Mix everything together completely so the salt, sugar, and yeast are evenly distributed throughout the flour.

    Because salt and sugar can hinder the fermentation of yeast, you coat each with flour first before mixing it all together.

  5. Take the dough out of the refrigerator, divide into 8 portions, and flatten each into a round.

    Fill with the filling.

    Pull the edges of the dough toward the center and pinch tightly with your fingers to seal well.

  6. Place the sealed side down and roll out thin with a rolling pin so the filling spreads evenly.

    Dust with a little flour as you roll so it does not stick.

    Roll as thin as possible until the filling shows through to make it crispy.

    The size I made was about 11-12 cm in diameter.

    Dab a little water in the center, place sesame seeds on top, and press down lightly with your hand.

FAQ

How thin should I roll the dough to get a crispy texture?

You need to roll it as thin as possible until the filling inside shows through the dough so that it turns out crispy when baked.

Is there anything to keep in mind when mixing the dry ingredients?

Since salt and sugar can interfere with yeast fermentation, coat each of them in flour first before mixing everything together.

Why is brown sugar mixed into the filling?

Using only dark brown sugar makes the color overly dark, so mixing in brown sugar helps balance the color.

Should I use dusting flour when rolling out the dough?

It is best to dust with a little flour as you roll so the dough does not stick to the rolling pin.
