Kiriboshi daikon is radish cut into strips and dried. It is sold in packs and normally cooked as a side dish.
This dish has many variations. Some mix hijiki (a black kind of seaweed), some mix boiled soy beans. It smells very strong so I haven't got any drive to actually eat it. But my husband likes this so I keep on cooking this from time to time-- despite the, uhm excuse me, farty smell. :P
A vegetarian for 12 years and a kitchen warrior since I moved in to Japan, my favorite battle has been winning over my husband's interestingly complicated taste buds.
