Ingredients

  • 2/3 cup yellow mustard seeds
  • 1 tablespoon mustard powder
  • 1 cup water
  • 2 tablespoons whole wheat flour
  • 1/2 cup white wine vinegar
  • 1/4 cup maple syrup (use the real thing)

Method

  • Blend the mustard seeds and powder in a spice grinder or coffee mill. Blend to the consistency you want (but leave it a little grainy).
  • Mix mustard powder and seeds with water in a glass bowl and cover with a cloth. Let sit on a countertop for 24 hours, stirring occasionally.
  • Stir flour into mustard base. Add vinegar and maple syrup and stir well. If you want a smoother texture, blend with an immersion blender.
  • Store at room temperature, tightly covered, stirring every day until it tastes the way you want it to. (I left mine out on the counter for about four days.).
  • Refrigerate. It keeps in the refrigerator for up to six months.
