How to make vegan fish sauce

If you’re a fan of Thai and southeast Asian food, you know that fish sauce is a key ingredient to many dishes, giving them their unique flavor. Fish sauce, also called nuoc mam or nam pla, is made from fermented fish and salt. I thought it would be interesting to try to come up with a vegan alternative, so here is how to make vegan fish sauce.

A food blogger friend suggested that the key taste to capture was umami, the savory taste found in soy-based foods.

I took seaweed, soaked it, added miso for the salty umami flavor, and blended it. It has a briny taste that is a pretty reasonable substitute for fish sauce. Note that the final product is not particularly appetizing in color, so you might want to keep this a secret ingredient in your recipes. If you’re following a soy-free diet, use chickpea miso instead of soy-based miso for this recipe.

Suitable for:
vegan, gluten-free, reduced-sugar diets

Not for:
low-sodium or migraine diets
