My grandma used to make this snack for me. The crispy grilled mochi and the nutty fragrant kinako (roasted soy flour) are so delicious together.
My grandma used to make this for me when I was a child, using the mochi rice cakes left over from New Year's.
If you soak the grilled mochi cakes in boiling water, they will turn soft. Combine the kinako and sugar in the ratio that you like. You can cut up the mochi cakes if you like too.
