Recipe: Lacto-fermented Honey Dill Mustard

Dill, mustard, and honey, all combined with whey and a bit of time, and voila! A condiment worthy of dipping and spreading on a variety of foods from corned beef to a cheese sandwich.


  • ½ cup mustard powder or ¼ cup whole seeds plus ¼ cup mustard powder
  • 3 Tbsp. whey, water kefir, or kombucha
  • 2 Tbsp. water
  • 3 Tbsp. dried or 5 Tbsp. chopped fresh dill
  • 3 Tbsp. honey
  • 1 tsp. sea salt


  1. If using seeds, pulse them partially in a food processor. Then put seeds, mustard powder, and the rest of the ingredients into a medium bowl. Stir to combine.
  2. Pour mustard into a jar, leaving at least 1 inch headspace.
  3. Cover tightly and leave on the counter for 2-4 days before moving it to the refrigerator.
