There is a craze at least my part of the world over eating roasted seaweed. Mosly Korean-style, but it's the same seaweed you find across most of East Asia. 10-20 years ago, MSG allergies were one of the first food allergy crazes and every wanted MSG-free food. MSG as an additive is harvested primarily from this type of seaweed. That's why the seaweed is so savory.
