📝 About This Recipe

Elevate your pantry with this sophisticated, handcrafted mustard that marries the sharp bite of yellow and brown mustard seeds with the elegant, anise-like aroma of fresh tarragon. Inspired by the rustic yet refined condiments of Burgundy, this recipe utilizes a cold-steeping method and a touch of honey to balance the natural heat of the seeds. It is a versatile masterpiece that transforms simple sandwiches into gourmet meals and serves as a luxurious base for vinaigrettes and pan sauces.

🥗 Ingredients

The Mustard Base

  • 1/2 cup Yellow mustard seeds (for a milder, creamy foundation)
  • 1/4 cup Brown mustard seeds (for heat and texture)
  • 2 tablespoons Dry mustard powder (adds immediate punch)

The Infusion Liquid

  • 3/4 cup Dry white wine (such as Sauvignon Blanc or Chardonnay)
  • 1/2 cup White wine vinegar (high quality with 5-6% acidity)
  • 1/4 cup Cold water (filtered)

Aromatics and Seasoning

  • 1/2 cup Fresh tarragon (leaves only, tightly packed)
  • 1 small Shallot (very finely minced)
  • 2 tablespoons Honey (or agave nectar for a vegan option)
  • 1.5 teaspoons Sea salt (fine grain)
  • 1/4 teaspoon Turmeric powder (for a vibrant golden hue)
  • 1/2 teaspoon White peppercorns (crushed)

👨‍🍳 Instructions

  1. 1

    In a non-reactive glass bowl or jar, combine the yellow mustard seeds, brown mustard seeds, and dry mustard powder.

  2. 2

    Pour the white wine, white wine vinegar, and cold water over the seeds. Stir well to ensure all powder is incorporated and no dry pockets remain.

  3. 3

    Cover the container tightly with plastic wrap or a lid and let it sit at room temperature for 24 to 48 hours. This allows the seeds to soften and the enzymes to activate, creating the characteristic mustard 'heat'.

  4. 4

    After the soaking period, you will notice the seeds have absorbed most of the liquid and expanded significantly.

  5. 5

    Transfer the soaked seed mixture into a food processor or high-speed blender.

  6. 6

    Add the minced shallot, honey, sea salt, turmeric, and white peppercorns to the processor.

  7. 7

    Pulse the mixture several times. For a coarse, 'old-style' mustard, blend for only 30-45 seconds. For a smoother consistency, process for 2-3 minutes until creamy.

  8. 8

    Add the fresh tarragon leaves last. Pulse just enough to finely fleck the mustard with green herbs without turning the entire mixture into a paste; this preserves the tarragon's delicate oils.

  9. 9

    Taste the mustard. Note that it will be quite bitter and aggressively pungent at this stage; this is normal and will mellow with refrigeration.

  10. 10

    If the mustard is too thick, whisk in an extra tablespoon of water or vinegar until your desired consistency is reached.

  11. 11

    Transfer the mustard into sterilized glass jars, leaving a small amount of headspace at the top.

  12. 12

    Refrigerate the jars immediately. Let the mustard 'mature' in the fridge for at least 3-5 days before using. This resting period is crucial for the flavors to harmonize and the bitterness to fade.

💡 Chef's Tips

Always use cold liquids when soaking seeds; hot liquid kills the enzymes that provide the mustard's spicy kick. Avoid using metal bowls for soaking, as the vinegar can react with the metal and impart a metallic taste. If you prefer a much sweeter mustard, increase the honey to 3 tablespoons or add a touch of brown sugar. Ensure your tarragon is perfectly dry before chopping to prevent the mustard from becoming watery. Homemade mustard lasts up to 6 months in the refrigerator, though the tarragon flavor is most potent in the first 4 weeks.

🍽️ Serving Suggestions

Slather onto a warm ham and gruyère croissant for a classic Parisian lunch. Whisk into a pan sauce for roasted chicken or pork chops to add depth and acidity. Serve as a dip alongside soft pretzels or a curated charcuterie board with sharp cheeses. Mix with a little olive oil and lemon juice for an exquisite dressing over grilled asparagus. Pair with a crisp glass of Chablis or a dry Riesling to complement the herbal notes.
