Cultured English Style Mustard (Spicy Yellow Mustard)

Cultured English Style Mustard (Spicy Yellow Mustard)

I am an unabashed mustard fan. Which is great considering things like ketchup and barbecue sauce are off the Autoimmune Protocol Menu. I often have a jar of cultured mustard in the fridge that I’m working through and one on the counter fermenting. Especially now that my spicy food intake is now limited.

The amazing thing about mustard is that you can somewhat control the heat of the finished product by adjusting the temperature of the liquids used to make it. The colder the liquid, the hotter the finished product. The hotter the liquid, the milder the finished product. The jar above I made with refrigerated fermented onion brine and it was flaming hot, whereas the jar of French style mustard pictured below (yes it is half eaten) was made with a just finished brine that was sitting in 85°F heat so the finished mustard was almost annoyingly mild. But palatable to the family and as turmeric and paprika are now off the table it’s the one I was going for most often. Paprika is a nightshade and nightshades have been triggering horrendous inflammation for me in the last few months. Turmeric is a close relative of ginger and my food allergy panel came back with a level 5 ginger allergy, I have found relief in avoiding it and it’s relatives.

So with all that explanation, I have below a very simple cultured mustard recipe. You may eat it straight away or leave it on the counter for a few more days to culture fully. Who doesn’t love probiotic condiments?!


  • 1 cup mustard powder or mustard seeds
  • 1/4 cup ice cold to hot water as desired (if you choose to use hot, add this FIRST then let it cool down before adding culturing brine.)
  • 1/4 cup apple cider vinegar with the mother
  • 1/2 cup fermented onion liquid/brine or kimchi liquid from previous ferment
  • 1/4 tsp garlic powder
  • 1 tsp pink salt
  • 1.5 Tbsp turmeric (optional)
  • 1/4 tsp sweet smoked paprika (optional)
French style (no turmeric or paprika). Obviously I like it this way. 😂


Place all ingredients in a food processor, blender or Vitamix (chop first if you’re using a normal blender) and puree. 

Alternatively if you are using mustard powder you can use an immersion blender or whisk it together vigorously. Transfer to a 1 Pint/500ml fermenting jar with air lock or a swing/clip top jar. Leave for 2-4 days on the counter to ferment. Enjoy!
