Ingredients

  • 1/4 cup yellow mustard seeds
  • 2 tablespoons brown mustard seeds
  • 1/4 cup mustard powder
  • 1/2 cup water
  • 1 1/2 cups cider vinegar
  • 1 small white onion, finely minced
  • 2 tablespoons firmly packed brown sugar
  • 1 teaspoon salt
  • 2 garlic cloves, minced
  • 1/4 teaspoon cinnamon
  • 1/8 teaspoon ground allspice
  • 1/4 teaspoon dried tarragon
  • 1/4 teaspoon turmeric

Method

  • In a small bowl, combine mustard seed and dry mustard; set aside.
  • In a 1- to 2-quart non-aluminum pan, combine remaining ingredients. Simmer uncovered, on medium heat until reduced by half, 10-15 minutes. Pour the mixture into the mustard mixture. Let mixture soak at room temperature 24 to 48 hours; adding additional vinegar if necessary in order to maintain enough liquid to cover seeds.
  • Process the seeds and mixture in a blender or food processor until pureed to the texture you like (this can take at least 3 or 4 minutes).
  • The mixture will thicken upon standing.
  • If it gets too thick after a few days, stir in additional vinegar. Scrape mustard into clean, dry jars; cover tightly and age at least 3 days.
