Old style recipe for whole grain dijon mustard, lightly cultured to add probiotic and enzymatic value to a meal of cooked foods.
Place mustard seeds, salt, whey and filtered water in a wide mouth pint sized jar. Blend well.
Cover the lid of the jar with a fine cheesecloth secured with a rubber band.
Leave on the counter for 3-5 days, removing the cheesecloth each day to stir the mixture and smell the bubbling ferment to assess progress.
When the slightly bubbly ferment begins to smell very "dijon-y" (this occurs on day 3 in Florida), blend the ingredients in the jar to a thickened paste with a handheld blender.
After blending to a paste, stir in 2 tablespoons of raw apple cider vinegar, screw on a tight-fitting lid, and refrigerate for a few days to allow the flavors to meld and temper the heat from the mustard seeds.
After refrigerating for a couple of days (up to 1 week), taste the mustard and adjust as needed to your personal taste preference. If you like the flavor as it is, do nothing additional. If you wish it a bit tangier, stir in 1-2 more tablespoons of raw apple cider vinegar. If you wish it less tangy, stir in 1-2 tsp of raw honey.
If desired, spoon the finished mustard into a clean, 8 ounce (1 cup) glass jar so that it looks very neat and tidy for bringing it to the table when needed.
Your cultured whole grain dijon mustard is now ready to enjoy. It will last for many months refrigerated!
