it's actually called nori, used to wrap sushi in and other stuff
there are 2 kinds , roasted and dried
can'r remember which the fish like better, i think dried...
The Kroger down the street from us has a sushi bar just inside the door. You can find a pretty good size package right there next to them in this Kroger.
i buy my nori at wal-mart. for 3 or 4 bucks you get a pretty good amount. It is roasted but i hear that dried is better for them. Serk knows of a place in garland i think that has dried in reallyl large packages.
