Songpyeon is a special rice treat made in the Korean home during Chuseok (秋夕) to celebrate the year’s harvest and to wish every family member good health. Songpyeon is made from 100% short grain rice cake dough that’s filled with various fillings then hand shaped and steamed.
Use a blender to coarsely chop mung beans. You can just season with salt for the most traditional taste or add honey for a sweeter filling.
Peel outer skin of Kabocha squash and cut couple think slices weighing about 50 grams. Cook in the microwave covered with wet paper towel for 40 seconds until fully soft.
Then close up edges to make a half moon shaped dumpling kind of a thing. Place on tray making sure they don't touch each other. Keep it covered.
When Songpyeon is cooked, turn heat off and let it cool in the steamer for 2-3 minutes.
This process of cold water bath and coating with oil helps Songpyeon to remain moist and from sticking to each other.
