Live and Learn (and hope no one dies along the way)
I worked at a Sushi Joint for about 7 years. During that time we assured all our customers that we did not use any MSG in anything we make. We did not have any MSG in the house ever.
Did you know that MSG comes from Kombu (seaweed)?
I didn't either.
Our sushi vingar was seasoned with Kombu, Every single piece of sushi that had rice with it had MSG in it.
Whoops.
