I had Kinakomochi ( Left in the photo )yesterday. Easy to make.
Grill rice cakes. Soak them into hot water. Drain off the water. Dress powder onto rice cakes. ( mix soy bean flour and sugar. I usually put 2 table spoons of soy bean flour and 1 table spoon of sugar )
Great snack or lunch, sometimes I have it for breakfast.
Kinako comes into a small plastic bag and we can easily find at super markets. Hope you can find one at your local stores or Asian market.
