Wow. Never knew there was so much behind Nori. Good Eats episode in order.
Mcarroll - your thoughts on feeding Nori with sesame oil/salt? Should I stop being lazy and just go back and find a raw, plain, one?
Only if it's unopened and you can return it – otherwise may as well use it or at least try it. You might notice the impact on your skimmer is a little more than normal, but maybe not. I wouldn't worry either way.
