It's fish based so it mostly goes really well with any fish meal (which we eat a lot of) - especially Asian. But in moderation it works just as well in place of salt for rich sauces, pasta sauce, gravy... It's kind of amazing.
I should mention it does have MSG in it, but I'm fine with that because all the bad press around MSG has been debunked anyway (it's the same amino found in tomatoes, cheese, mushrooms). It's mostly the fish compounds that make it unique and so so good.
