There are some culinary things you just have to do when traveling, right? Like trying Dijon mustard in Dijon, France. One of the great places to shop for multiple different Dijon mustard is the Les Halles, the indoor market place in Dijon. Imagine our surprise when we heard that Dijon mustard is far from being a "champagne of mustard" and while Dijon mustard was invented in Dijon, today most mustard described as "Dijon" is manufactured elsewhere. The Dijon mustard in Dijon, France is in fact made almost exclusively from Canadian mustard seed!
