Gather these items before you start, and you’ll be well prepared to create flavorful, homemade fermented mustard that is both tangy and healthful.

Preparation Steps

Starting your mustard fermentation journey begins with ensuring everything is clean and prepared. Follow these step-by-step instructions to set up your fermentation project properly.

Cleaning and Sanitization

Proper cleaning and sanitization are crucial to prevent unwanted bacteria from spoiling your mustard. Begin by thoroughly washing all your tools and containers. Use hot, soapy water to clean the glass jars, non-reactive mixing bowls, wooden spoon or silicone spatula, measuring cups, and spoons. After washing, rinse everything with boiling water to ensure no soap residue remains. To further sterilize your equipment, you can soak the items in a solution of 1 tablespoon of unscented bleach per gallon of water for at least one minute. Rinse again with boiling water, and allow all items to air dry completely before use. This step ensures that your equipment is ready for safe mustard fermentation.

Soaking the Mustard Seeds

Soaking the mustard seeds is the first step in the fermentation process. Take 1 cup of mustard seeds, and ensure they are clean and free from debris. Place the seeds in a non-reactive bowl, and cover them with three cups of water. Use room temperature, filtered water to avoid introducing any impurities. Allow the seeds to soak for 24 to 48 hours, which will help soften them and activate the germination process. This soaking period is essential as it initiates the release of enzymes that are key to developing the complex flavors in fermented mustard. Make sure to stir the seeds occasionally during the soaking process to ensure that they are evenly hydrated.

Fermentation Process

After soaking the mustard seeds, you are ready to mix them with the other ingredients and begin the fermentation stage, which develops those unique, tangy flavors.

Mixing the Ingredients

1. Prepare Your Mixture:

    • Drain the soaked mustard seeds and transfer them to a mixing bowl.
    • Add 1 tablespoon of sea salt and 2 tablespoons of whey (if not using whey, you can substitute with an extra tablespoon of salt).
    • If you prefer a spicier flavor, incorporate a few crushed garlic cloves or a teaspoon of chili flakes.

    2. Blend the Ingredients:

      • Use a food processor to blend the ingredients together until you achieve a coarse, paste-like consistency.
      • Optionally, for a smoother texture, continue blending until the mustard reaches your desired fineness.

      3. Adjust the Flavor:

        • Taste your mustard paste and adjust the seasoning, adding more salt or spices if needed.
        • Remember, the flavors will continue to develop and intensify during fermentation, so it might taste stronger after fermenting.

        Storing for Fermentation

        1. Choose the Right Container:

          • Transfer the mustard paste into a clean glass jar that can be sealed tightly.
          • Ensure the jar is large enough to leave at least 1-2 inches of air space at the top after filling.

          2. Secure the Contents:

            • Press down the mustard in the jar to remove any air bubbles.
            • Cover the surface with a cabbage leaf or a piece of parchment paper before sealing the jar. This helps keep the mustard submerged and reduces exposure to air.

            3. Store the Jar:

              • Place the jar in a cool, dark place for fermentation. Ideal temperatures for mustard fermentation are between 55°F and 75°F.

              4. Check Regularly:

                • Open the jar every other day to release any gases that build up — this process is also known as ‘burping’ your jar.
                • This also gives you a chance to check the progress of the fermentation, ensuring there are no unwanted molds or odors.

                5. Observe Changes:

                  • Notice any color changes or bubbles forming, which are signs that the fermentation is actively occurring.
                  • The mustard generally starts to smell tangy and pungent as it ferments, which is normal and desired.

                  6. Taste Test:

                    • After about 5-7 days, start tasting your mustard to decide if it has fermented enough for your liking.
                    • Depending on your taste preferences and the room temperature, full fermentation can take anywhere from one to several weeks.

                    Post-Fermentation Tips

                    Once your mustard has completed its fermentation cycle, a few simple checks and adjustments can ensure it’s perfectly flavored and ready for use.

                    Testing for Doneness

                    Testing whether your mustard is fully fermented is key to enjoying its optimal flavor and texture. Start by observing the color; it should be uniformly bright and slightly darker than when it started. Smell the mustard; the aroma should be pungent yet pleasant, with no off odors. Finally, taste a small amount. Properly fermented mustard will taste tangy with a depth of flavor that wasn’t present before fermentation. If the mustard tastes overly sharp or bitter, it might need more time to ferment, so consider letting it sit for a few more days.

                    Adjusting Flavors

                    After determining that your mustard is fully fermented, you might find the need to adjust the flavors according to your preference. If the mustard is too bitter, you can add a small amount of honey or sugar to soften the edge. For a creamier texture, mix in a little bit of vinegar—it will not only smooth out the consistency but also stabilize the flavor. If the mustard is too mild, you can boost its pungency by stirring in a bit more mustard powder. Always blend any added ingredients thoroughly and let the mustard sit for at least another 12 to 24 hours before doing another taste test, allowing the flavors to meld beautifully.

                    Storage and Usage

                    Once your mustard has fermented to your liking, proper storage and usage are key to maintaining its quality and enhancing your dishes.

                    How to Store Fermented Mustard

                    To ensure that your homemade fermented mustard retains its flavor and benefits, you should store it correctly. Transfer the mustard into airtight containers, preferably glass jars, which help preserve the taste and prevent contamination. Place these jars in the refrigerator where the fermentation process will slow down significantly, keeping the mustard fresh. Properly stored, your fermented mustard can last for up to six months in the refrigerator. Always use a clean spoon each time you scoop out some mustard to prevent introducing any bacteria into the jar, which could spoil the mustard.
