I'm looking for an actual recipe (with measurements, not just ingredient list) for vegetarian fish sauce. As I don't really know what the real sauce tastes like, and therefore can't just throw something together, actual measurements/proportions would be greatly appreciated. Authentic Thai or Vietnamese also appreciated. BTW, I'm not asking for veg. oyster sauce, which is already available in Asian markets. I've heard suggestions for recipes that include fermented bean sauces or fermented tofu if anyone has a recipe like that.
