Vegan Fish Sauce

December 11, 2015

Test Kitchen-Approved

Author Notes: When I dine at Vietnamese and Thai restaurants and request that they leave out the fish sauce, ubiquitous in South Asian cuisine, the dishes sometimes taste as if they are lacking something. That “something” is fish sauce, South Asia’s “secret ingredient” that adds oomph to dishes, injecting that special flavor that you can’t quite put your finger on.

Here is my vegan version that can be universally added to Asian-style dishes, lending them that extra “something.” And the secret ingredients in my fish sauce? Wakame, a seaweed, and the liquid from those jars of fermented tofu, a somewhat stinky Chinese condiment made by pre-serving tofu in wine, vinegar, and other ingredients for months (don’t be put off by the description!). Give it a try and then use it in everything from green papaya salad to Thai-style curries.

For the fish sauce:

  1. Combine all of the ingredients in a jar and mix or shake well. Store in the refrigerator for up to 2 months. Shake well each time before using to redistribute the wakame.

For the wakame powder:

  1. Put the wakame in a blender and cover tightly. Process until it is completely pulverized. Wait a second for the wakame dust to settle before removing the lid, or you’ll lose some of it as it disperses into the air. Store in a covered jar at room temperature.

So I made this to the T but found it too sweet. This is the modifications I did.

2g wakame seaweed
2 t total of sea salt
I boiled the water and threw in a sheet of dashi kombu seaweed

Doing that helped bring the salt content flavor through and the sea umami flavor.

I’ll let it set to room temperature and then put it in the fridge.

Really delicious recipe. I had to make an adjustment but I found it's not as strong as real fish sauce so I just had to use double the amount of fish sauce called for in the recipe I used it in. I didnt have time to shop for any wakeme so I just used some dried seaweed snacks. It was a little oily when I put it through the processor but it gave the needed ocean flavor needed. Kelp powder would have probably worked too.
