hi guys -- thank you for your replies so far. the question i posted is interesting to me in that the answer seems so elusive, like it's some kind of "secret" ingredient . worm@work was right, it's called chukka salad in restaurants [and like kent said, it's available often in bags or containers already prepared] but i am not so sure about the "chukka seaweed" part. i know there is seaweed called OGO from Hawaii but have no clue what the texture of it is like. worm is right though, it's addictive -- and good enough to buy in a 10 lb bag!! tokaris - i have a feeling it might be made with the ao tosaka which would explain the texture part. i will dissect the salad the next time i get it to see if the edges are frilled or not. i know that it is cut into to strips and is usually a bright green. i have never had the kuki wakame you mention but i have seen it usually salted in bags. what does the word kuki mean in Japanese? i still don't get the agar part of it however. hiroyuki, i found that picture somewhere on the net. it is not a very good one for detail, i know. i think the salad is on top of regular iceberg lettuce. it is not served here that way normally, just in a small bowl but i imagine different places serve it differently. i have never had the other kombu you mention; i have only used the very large one used for making dashi. in any case, thank you all for your help -- it's more answers than i had previously!
