Ingredients

  • 3/4 cup brown mustard seeds
  • 1/4 cup yellow mustard seeds
  • 1 cup dark beer, or as needed
  • 2 cloves garlic, minced
  • 1/2 cup apple cider vinegar
  • 2 tablespoons brown sugar
  • 1 teaspoon salt
  • 1/2 teaspoon ground black pepper
  • 3 half pint canning jars with lids and rings

Method

  • Soak brown and yellow mustard seeds with dark beer in a large bowl set in the refrigerator for 24 hours. If the seeds soak up the beer too quickly, add more beer.
  • Transfer the soaked mustard seeds to a food processor along with garlic, apple cider vinegar, brown sugar, salt, and black pepper. Pulse until desired consistency is reached.
  • Sterilize the jars and lids in boiling water for at least 5 minutes.
  • Pack the mustard into the hot, sterilized jars, filling the jars to within 1/4 inch of the top.
  • Run a knife or a thin spatula around the insides of the jars after they have been filled to remove any air bubbles.
  • Wipe the rims of the jars with a moist paper towel to remove any food residue. Top with lids, and screw on rings.
  • Refrigerate the jars of mustard for 2 weeks before using.
