I see!
I haven’t heard of this brand, but I read through the info and it sounded very nice. This is something you eat with rice. You can chop them into fine pieces and mix with cucumber slices as well, but it is best to eat with rice.
It is seaweed, that had been cooked with soy sauce and sugar and sake and mirin, and then dried. It is salty. The product has got some kind of governmental prize twice, so that the quality is promised, I think.
Why don’t you give it a try?
