Making potato rice cake without fail

Hello?
I'm the daughter-in-law of a servant's family.
I made and ate potato rice cake at home on vacation.
I had two Songpyeon filling.
I thought it was a good thing that we each ate our favorite songpyeon.
It's not hard to make potato rice cake without failure.
Subscribers, please enjoy your meal.^^
Ingredients for making potato rice cake (200 ml cup)
5 raw potatoes 600g
2 cups potato starch
1 cup cornstarch
3/4 cups frosty tae beans
3/4 cups yellow beans
4 tablespoons non-refined raw sugar
2 tablespoons sesame seeds
1 tablespoon sesame oil
Salt
If you can't eat it at once, steam it in a steamer and when it's hot.
Freeze it and take it out when you want to eat it.
It's chewy and delicious.
Please refer to the video for the process of making it.^^
