Homemade Pickled Mustard Seeds offer a tangy, mildly sweet, and savory burst of flavor, perfect as a garnish for toasts, salads, roasted meats, and vegetables. This easy-to-make condiment combines yellow mustard seeds with a simple vinegar-based brine, resulting in a vibrant, versatile addition to enhance your dishes.

Ingredients

Pickled Mustard Seeds

  • 4 ounces yellow mustard seeds
  • 1 cup unseasoned rice vinegar
  • 2 tablespoons sugar
  • 3 teaspoons kosher salt
  • 2 cloves garlic, peeled and lightly smashed (optional)

Instructions

  1. Prepare the Mustard Seeds: Place the mustard seeds into a 16-ounce glass jar, filling about one-quarter of the jar’s volume. If using garlic, add the peeled and lightly smashed garlic cloves to the jar.
  2. Boil the Brine: In a small saucepan, combine the rice vinegar, sugar, and kosher salt. Bring the mixture to a boil over medium-high heat, then reduce the heat and simmer until the sugar and salt fully dissolve.
  3. Cook Mustard Seeds: Place the mustard seeds in a saucepot, cover with cold water, and bring to a boil. Once boiling, strain the mustard seeds using a sieve or fine mesh strainer, then transfer them to the prepared glass jar.
  4. Combine Ingredients: Pour the hot vinegar brine over the mustard seeds and garlic in the glass jar, ensuring the seeds are fully submerged.
  5. Cool and Store: Let the jar cool to room temperature or until it’s cool enough to handle, about 30 minutes. Seal the jar with a lid and refrigerate. Allow to rest for 2 to 3 days for the best flavor before serving. Store refrigerated for up to 2 weeks.

Notes

  • If using a larger 32-ounce Mason jar, double the brine ingredients accordingly for proper coverage.
  • To avoid spilling hot liquid when pouring into the jar, use a large container with a pouring lip, such as a glass measuring cup.
  • For a spicy variation, add slices of hot pepper or a pinch of red pepper flakes to the jar before adding the brine.
  • The mustard seed measurement can vary by about an ounce without affecting the outcome significantly.
  • Store pickled mustard seeds in a tightly sealed nonreactive container in the refrigerator for up to 2 weeks.
  • Freezing is not recommended for this recipe.
