Mustard is so easy to make and only requires a few ingredients. You can add different flavors to make a fun flavor combination. It's so surprising to me how the store bought mustards have many additives and preservatives. Making your own is good for you and tastes 100 times better than the store bought version. This mustard has a nice kick of spice to it, so beware of the heat. Plus it's Whole30 approved!
optional additional ingredients are white wine, beer, cider, honey, caraway, coriander, rosemary, and chillies (not Whole30 approved)
Place both mustard seeds in a mason jar. Pour in the vinegar and close the lid tightly. Leave on the counter overnight.
Next morning place the mustard seeds and the added flavors into a food processor and blend until you get a desired consistency. The yellow mustard will grind more and the brown will stay whole. That's how you get the stone ground looking mustard.
Adjust seasoning to your liking, if it's a bit thick you can add a little bit of water to make it more thinned out.
