Easy Recipe for 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 raw apple cider 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.
- 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. Once the mustard is done fermenting, I blend it in my blender for a smooth texture.
- Apple Cider Vinegar: I think raw apple cider vinegar is the best for this recipe. You can also use white vinegar or rice vinegar.
- Sauerkraut Brine: You can use the brine from homemade sauerkraut or you can use the brine from our Cultured Guru 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 fresh horseradish usually found in a jar in the refrigerated section of the store.
- Maple Syrup: Most mustard recipes call for a type of sweetener, usually sugar. I prefer to use 100% pure maple syrup instead of sugar.
- Spices: This recipe requires Garlic, Onion, Tarragon, Cinnamon, and Turmeric.
How to Make Lacto-Fermented Mustard
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 veggie 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! yay! 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 an easy way to add some probiotic bacteria to any sandwich or burger.
