Ingredients
  • ¼ cup yellow mustard seeds
  • ¼ cup brown mustard seeds
  • ½ cup apple cider vinegar
  • ¼ cup beer
  • 1 tsp honey optional
  • ¾ tsp kosher salt optional
Recipe
  1. Mix the seeds, vinegar, and beer in a glass or ceramic vessel. Cover and let soak at room temperature overnight, or up to 2 days. The seeds will bloom and grow in size.
  2. Add the salt and honey, if using.
  3. Blend until combined and thickened, about 1-3 minutes total. Keep pulsing until your desired consistency is achieved. It should be a continuous spread with some bits of whole grain mustard seeds intact.
  4. Scoop mustard into a glass or ceramic vessel and either serve or store in the fridge for a mild mustard. For a spicier mustard, let it sit at room temperature until your desired spice level, up to 2 days.
Recipe Notes

Store in an airtight vessel in the refrigerator for up to 3 months, if it lasts that long!
