  • 1/4 cup fish sauce see Note 1 for Whole30
  • 2 tablespoons coconut aminos plus more as desired, see Note 2
  • 1/4 cup plus 2 tablespoons plain sauerkraut juice see Note 3


  • Combine all ingredients in a bowl. Strain into a jar or bottle and refrigerate. Keeps in the fridge at least 2 weeks.


Note 1
Make sure your fish sauce is compliant and totally sugar free if on a Whole30. Red Boat Fish Sauce is the only brand I know of, and it's excellent!
Note 2
You can increase the coconut aminos as desired. Doing so will deepen the color and reduce the intense saltiness of the original recipe. However, I prefer this soy sauce substitute with 2 tablespoons coconut aminos per 1/4 cup fish sauce and 1/4 cup plus 2 tablespoons sauerkraut juice.
Note 3
Make absolute sure that your sauerkraut is plain, not Garlic Dill, Red, etc. I like a fresh, refrigerated sauerkraut, like Wild Brine.
Note 4
Serving size is 1 tablespoon. Recipe makes 3/4 cup.
