Prepare the mochi – If using fresh mochi, cut it into bite-sized pieces. If using store-bought mochi blocks, lightly toast or steam them until soft and chewy.
Toast the mochi (optional) – Grill or pan-toast the mochi pieces until lightly browned and puffed.
Prepare the kinako coating – In a bowl, mix kinako (roasted soybean flour) with sugar to taste.
Coat the mochi – Roll each mochi piece in the kinako-sugar mixture until fully coated.
Serve – Place coated mochi on a plate. Optionally, drizzle with a small amount of soy sauce or kuromitsu (Japanese black sugar syrup) for extra flavor.
Enjoy – Serve immediately while the mochi is soft and chewy.
