Brief History

The story behind National Mustard Day starts with Barry Levenson, whose love for mustard began in the most unexpected way. In 1986, after his favorite baseball team suffered a heartbreaking loss, he wandered through a grocery store looking for something to lift his spirits, heard a voice tell him, "If you collect us, they will come," and purchased a dozen jars of mustard.

What started as one purchase quickly turned into a remarkable hobby. Before long, his collection had grown so large that he left his career as a lawyer to pursue his passion. In 1992, he opened the mustard museum in Mount Horeb, Wisconsin, giving fellow mustard fans a place to explore his unique collection. To spread the word, he launched National Mustard Day with a modest celebration featuring hot dogs, games, and family-friendly fun.

As interest grew, the museum moved to a larger location in Middleton in 2009. Today, it houses more than 6,000 varieties of mustard from all 50 states, proving how one person's unusual passion became a beloved tradition enjoyed by visitors from around the world.

You do not have to travel to Wisconsin to enjoy National Mustard Day. There are plenty of fun ways to celebrate right in your own kitchen while exploring the rich history and flavors of mustard.

  • Try a Guided Taste Flight

Create a tasting lineup with five different mustard styles, starting with the mildest and working toward the boldest. Begin with classic American yellow mustard, known for its bright color from turmeric. Next, sample tangy Dijon, then hot English mustard made by mixing mustard powder with water. Finish with whole-grain mustard for its crunchy texture or a spicy horseradish blend. It's a simple and enjoyable way to discover how different ingredients create unique flavors.

  • Cook a Legacy Meal

Bring history to your dinner table by recreating an ancient recipe. Blend crushed yellow mustard seeds with pine nuts, honey, and vinegar to make a sweet and tangy glaze inspired by a fourth-century Roman recipe. It pairs wonderfully with roasted pork.

  • Make Medieval Mustard Balls

Another fun idea is making medieval English balls by mixing crushed seeds with cinnamon and cider. You can dry these small spheres to store them safely for many months. When you are ready to eat, just add vinegar to turn them back into paste.
