To serve

  • ½ tsp sesame seeds


  • Fry the garlic and ginger in sesame oil for about 30 seconds - 1 minute on a medium/ low heat until fragrant.
  • Add the Tamari, coconut aminos, low carb sweetener, water, apple cider vinegar and spices. Bring to the boil, then cook for 2 minutes on a low simmer.
  • Whisk in ¼ tsp xanthan gum and heat until it thickens and reaches your desired consistency. Mine took about 4 minutes.


1.2g net carbs per tablespoon of sauce. Makes ½ cup / 8 tbsp of sauce.  
Store in a sealed glass jar in the fridge for up to one week. (It probably lasts much longer than that because of the vinegar but mine was always gone within a week.)
Use as a sauce or a marinade. Simply marinate your meat or fish or chicken for about 20 minutes before grilling or frying.
