This staple condiment is delicious and full of fermentation goodness when created with whey. Mix yellow and brown mustard seeds to create more or less sharpness in the mustard. Yellow mustard seeds have a milder flavor.

- ⅔ cup water
- ¼ cup raw apple cider vinegar
- 2 tablespoons raw honey or maple syrup
- ¼ cup whey
- 2 tablespoons sea salt
- ¼ cup fresh lemon juice (about two medium lemons)
- 4 cloves garlic, crushed
- With a blender or food processor on pulse setting, partially grind the dry mustard seeds, leaving most of them whole.

- Place the mustard into glass jars leaving one inch of headroom. Cover the jars tightly.
- Place the jars on the counter to ferment at room temperature for 2 to 3 days.
