A long time ago I read an article in a scientific journal about a seaweed extract that the Japanese use in almost everything they cook.
While the extract is tasteless and odorless, the research showed that it potentiated the effect of adding monosodium glutamate (msg). In other words, put some seaweed extract into your dish, and you need between 200 to 1000 times less msg to get the "msg taste effect" - which is why the Japanese use msg in most of their cooking, and do not suffer the health effects of habitual msg use that are seen in China, because they use a lot less msg.
O yez, I know so much, but I can't remember the name of that seaweed extract ... can somebody please tell me?
