Easy Fermented Mustard

The way we ferment mustard is different from vegetable fermentation processes. Since mustard seeds are a dry good, they need to be fermented in a different way to ensure a safe, preserved product.

For this recipe we used already acidified, probiotic sauerkraut brine in addition to vinegar to create probiotic mustard.

When I make mustard from scratch, I always let it ferment and age for about a month. The aging process helps to cut the initial bitter flavor. Mustard seeds and mustard powders are initially very bitter and with time the bitterness dissipates.

Ingredients For Mustard Fermentation

• Mustard Seeds and Mustard Powder: Obviously, this is the main ingredient in mustard. I like to use a mix of brown and yellow mustard seeds with yellow mustard powder. In this fermented mustard recipe you have the option of blending it for smooth mustard or keeping it course.
• Vinegar: Any vinegar will work here. I think white vinegar or apple cider vinegar give the best flavor. You can also use rice vinegar.
• Sauerkraut Brine: for this, you use the brine from homemade sauerkraut
• Sea Salt: As always, I suggest using unrefined sea salt. Any type of unrefined sea salt works well.
• Horseradish: I LOVE horseradish in mustard recipes. I think the flavor pairs so well with mustard seeds. You can use horseradish powder, but I suggest using the prepared horseradish found in a jar in the refrigerated section of the store.
• Honey or Maple Syrup: Most mustard recipes call for a type of sweetener, usually sugar. I prefer to use honey or 100% pure maple syrup instead of sugar.
• Spices: This recipe requires Garlic, Onion, Tarragon, Cinnamon, and Turmeric. Which spices you use depends on the type of mustard you want to make.

Fermented Mustard Seeds

I prefer my mustard to be lacto-fermented for three main reasons.

The first being digestibility. Sometimes I like to go overboard with the mustard on burgers and sandwiches… and that sometimes results in a bit of indigestion. BUT when it’s fermented, I have no issues. So more mustard, fewer problems!

Next, I prefer the flavor. Mustard is a very flavorful condiment, but did you know that when it’s fermented the flavor is even better?

Lastly, I love making this fermented condiment because it’s easy to add some probiotic bacteria to any sandwich or burger.
