Why is my mustard bitter?

Bitterness usually comes from cooking the mustard too hot or too long. Keeping the heat low and steady helps maintain a balanced flavor.

Can I can this mustard for long-term storage?

You can use proper hot-water bath canning methods, but storing the mustard in the refrigerator is simpler and reliable for most home kitchens.

Freshly made mustard is naturally sharp. The flavor mellows over several days in the refrigerator, becoming more balanced.

The mustard should form a thick paste before adding vinegar, then loosen slightly afterward. It should coat a spoon and slowly drip off when ready.

This homemade mustard recipe delivers bold, sharp flavor using simple pantry ingredients and a slow simmer technique for better texture and balance.
