karamimochi; mochi with grated daikon and soy sauce
A traditional Japanese snack: pounded rice cake topped with a spicy mixture of grated daikon radish and soy sauce, sometimes with other seasonings.
In winter, I often eat karamimochi.
The karamimochi at this shop has plenty of grated daikon and is delicious.
Compound of 辛味 (からみ, 'spicy taste') and 餅 (もち, 'mochi'). The name directly describes the dish: mochi with a spicy flavor from grated daikon.
