While making pickled mustard seeds is easy, one chemical reaction is important to clarify because it affects the final taste of pickled mustard seeds.

Cold water effect

Mustard seeds contain a chemical compound calledmyrosinase, which is responsible for theirpungent and zingy flavor. Soaking mustard seeds incold watercan activate myrosinase, releasingpungent and spicy flavors.

However, if you’re aiming for amilder flavor, use warm water orwarm liquids, as the higher temperature can slow down the enzymatic reaction and result in milder, less spicy mustard seeds.

Pickled Mustard Seed Recipe

I have been using brown mustard seeds for this recipe and aim for pickled mustard seeds’ milder, mellow flavor. Thus, I do a long slow cook. However, for a spicy version, cover it withcold waterinstead. To remove the bitter tannins, I will be blanching the seeds.

First step – Blanching the seeds

Start by pouring one cup of water into a small saucepan and bringing it to a boil. Once the water is boiling, add the mustard seeds, gently stirring them to ensure they are fully submerged. Allow the seeds to boil in the water for 1 minute. Then, strain through a fine mesh strainer and rinse them thoroughly under cold running water. Next, return the seeds to the saucepan and repeat this process three times. This will help soften the seeds and eliminate their bitterness.

Second step – Prepare the brine

Combine rice vinegar, apple cider vinegar, brown sugar, one piece of ginger, and one rosemary strip, and salt in a small pot, and stir to combine and dissolve all ingredients.

The third step – Strain and transfer the mustard seeds into a brine.

Add the drained mustard seeds to the pot with the brine and stir to ensure they are coated evenly. Bring to a boil, reduce the heat to low and simmer gently for approximately 10-15 minutes, stirring occasionally. Continue simmering until the seeds become tender and plump. Over time, as most of the brine evaporates, the seeds are gelatinous. To prevent fast evaporation, you can cover the saucepan with a lid. If theseeds have absorbedall of the liquid splashes of vinegar or water, remedy this.

Fourth step: Transfer to a jar

Remove from the heat and allow to cool to room temperature. Remove rosemary sprig and ginger and transfer to a clean jar or to a sealableairtight container and kept refrigerated. It will stay fresh in the fridge for several months.

How Long can I use Pickled Mustard Seeds?

Pickled mustard seeds can stay good in the fridge for a few months. Then, if they start to dry out or become too thick because they absorb the liquid, add a little more vinegar and stir it in to keep them moist.
