Partially grind the seeds in a spice grinder, coffee grinder, or mortar and pestle. This is one job that a small food processor can’t do, the seeds are too small. I left about half of the seeds intact for texture in my mustard.
Mix the seeds with the mustard powder, vinegar, cider, salt and honey. Stir until smooth and lump free. If it seems too thick, add more cider, if it seems a little thin, add more mustard powder, the consistency is up to you. The mustard will thicken a bit as it sits.
Pour into a seal-able glass jar and let rest for a day before using to mellow out the bitter compounds in the mustard. I keep mine in the refrigerator.
