Hello.
I'm the daughter-in-law of the family.
My husband likes rice cakes, so he often makes and eats rice cakes.
It is very delicious to make rice cakes with just one potato starch powder.
They made potato starch powder in the countryside and sent it to me
I made it, but it was okay.
If you want to use the starch powder that's sold in the market
If you steam two potatoes and mix them in the batter
You can make it and eat it without failure.

ingredients for making
400g potato starch powder
2 cups of green kidney beans (400ml)
a half-salt drink
1 tbsp of alcohol per non-fixed source
1 tablespoon of sesame oil
