  • Bring the mixture to a boil over medium-high heat and then reduce the heat to low. Continue to simmer until the seeds have absorbed most of the brine, have plumped slightly and have a pleasantly pop-in-your-mouth texture, about 35-40 minutes. If the seeds begin to dry out before the desired texture is achieved, simply add another tablespoon or two of water and continue cooking as directed.

FAQs

What do pickled mustard seeds taste like?

They are indeed mustard-y, pleasantly pungent but with a little sweetness and tang. The texture of pickled mustard seeds is just as delightful as their taste....they are a bit gelatinous, tender on the inside but with a bit of a "pop" when you bite into them, like caviar.

How do I use pickled mustard seeds?

They are good with so many different savory dishes, especially those that are rich such as cheese, salami, ham, pâté, eggs, smoked or cured salmon and creamy salads (such as this shrimp salad). Pickled mustard seeds are also quite nice swirled into a simple vinaigrette and drizzled over cooked asparagus or green beans. Really, anywhere that mustard would be welcome, so would pickled mustard seeds.

How do I store pickled mustard seeds?

Store them in an airtight container (I use a small mason jar with a lid) in the refrigerator.

How long will pickled mustard seeds last in the refrigerator?

Pickled mustard seeds will last up to a month in the refrigerator.

Can I use a different type of vinegar in this recipe?

Yes! Feel free to use apple cider vinegar or champagne vinegar in place of the white wine vinegar.

Can I use a different type of sweetener in this recipe?

The brown sugar is such a nice pair with the mustard, but you can also use granulated sugar, maple syrup or honey.
