On fish sauce, there's a strange kind of 'vegan fish sauce' that you can buy in some Asian shops. (I've got it from one of the Vietnamese shops in Mare Street.) I have yet to work out how to use it. It's a bit like a thin sweet chili sauce. So far, I haven't been able to detect any properties that would move it close to fishy fish sauce.
