The History of Mustard - The Ancient Condiment that Conquered Europe

You probably think of mustard as just the yellow condiment sitting next to ketchup. But this simple sauce has a history stretching back thousands of years, from ancient medicine and Roman kitchens to the mustard mills of Europe. And one of the most surprising parts of that story happened in 1854, when Munich mustard maker took a sharp French-style mustard and mixed in caramelized sugar and spices. The result was a sweet mustard that would become one of Bavaria's most distinctive flavors. So how did the same ancient seed produce completely different mustard traditions across Europe? How did mustard go from an ancient mixture of crushed seeds and grape must to the fiery mustard of Dusseldorf and the sweet mustard of Bavaria? To understand that, we have to go back almost 3,000 years. Way before Rome was even a thing, people in India and the Middle East were already crushing up mustard seeds and using them. Mustard seeds are tiny, but they're hiding a kind of fire inside them. Crush one, add a little liquid, and suddenly it lets off this sharp, burning heat. That natural heat would eventually make mustard useful as a condiment. But the Romans took it a step further. Roman cooks mixed crushed mustard seeds with grape juice that hadn't fully turned into wine yet, called must. The mixture created a sharp, tangy paste. They called this mixture burning must, or mustum ardens in Latin. That Latin name eventually gave us the word mustard. So every time you put mustard on a hot dog, you're basically using a word that started more than 2,000 years ago in ancient Rome. The Romans used mustard as part of their cuisine, and the condiment later became established across Europe. Now fast forward to after the fall of Rome. Spices like pepper became expensive because they had to travel huge distances to reach European markets. Pepper was so valuable that it could even be used for rent and other payments. In 1337, for example, the king received one pound of pepper as part of a rent payment from the mayor of Launceston. Mustard was different. It could be grown locally, giving ordinary families a cheap way to add flavor to bread, boiled meat, and salted fish. By the 14th century, mustard was already part of established European food traditions. And by 1634, Dijon's mustard makers were subject to craft regulations, showing that mustard making had become an organized trade. By then, mustard had become a regional European condiment, with different areas developing their own textures, strengths, and traditions. One of the most influential traditions emerged in the French city of Dijon, which eventually became famous for its distinctive style of mustard. In 1856, Dijon mustard maker Jean Neijon changed the recipe by replacing vinegar with verjuice, the acidic juice of unripe grapes. The change gave the mustard a distinctive acidity and helped shape the French-style mustard that became widely recognized. French mustard would also influence mustard makers beyond France. As European food traditions spread across borders, producers in neighboring countries adapted French techniques and recipes to suit local tastes. This is one reason mustard developed such different regional identities across Europe, even though the basic ingredient remained the same. One of the best places to see this regional identity was Düsseldorf in western Germany near the Rhine River. In Germany, it became part of regional food culture, with different cities developing their own traditions and flavors. Düsseldorf has one of Germany's oldest documented mustard traditions. In 1726, a mustard business was established in the city, and the tradition later became closely associated with mustard maker Adam Bernhard Burgrath. His initials, ABB, eventually became the name of one of Düsseldorf's best-known mustard traditions. The mustard associated with ABB became known as Düsseldorfer Mustert. It was a dark, strong mustard with a sharp flavor, made from mustard seeds and brandy vinegar. The ABB mustard also became recognizable because of its packaging. It was traditionally sold in small stoneware pots marked with the letters ABB and an anchor. The anchor was connected to Düsseldorf's city symbol and became part of the mustard's visual identity. That little mustard pot even made its way into art. Vincent van Gogh included an ABB mustard pot in one of his still-life paintings from the 1880s. So a simple mustard container from Düsseldorf ended up becoming part of the visual record of European art. But Düsseldorf's mustard story wasn't just about one company. Over time, the city developed a reputation as an important center of mustard production, and several local mustard varieties became connected with the city's food culture. Mustard was served alongside the hearty foods common in the region, where a strong condiment could add plenty of flavor to meat and other traditional dishes. So by the time we reach the 19th century, Germany already had a long-established mustard tradition in the West. But then we travel south. In Bavaria, the mustard story takes a completely different direction. In 1845, Johann Conrad Devillet founded his mustard business in Munich. At first, he made medium-hot and hot mustards in the French style. Then, in 1854, he made a change that would create one of Bavaria's most recognizable condiments. Devillet mixed caramelized sugar and a special blend of spices into his spicy mustard. The result was sweet mustard. That might sound unusual if you're used to strong mustard. Why make mustard sweet? The answer becomes clearer when you look at Bavarian food culture. One of Bavaria's most famous foods is Weisswurst, a mild white sausage traditionally associated with Bavaria. Instead of overpowering that delicate flavor with an intensely hot mustard, sweet mustard offered a very different combination. Its sweetness and mild spice complemented the sausage instead of competing with it. The pairing became part of a larger Bavarian food tradition. Weisswurst with sweet mustard often served alongside a soft pretzel. And Devillet's sweet mustard didn't remain a small experiment. The company continued producing it according to its original recipe, and the mustard became closely associated with Bavarian identity. Devillet itself describes the sweet mustard created in 1854 as an iconic product. The company's history continued to grow as well. In 1874, Devillet became an official purveyor to the Bavarian royal court, supplying mustard to members of the royal family. And this gives us a fascinating contrast. Both traditions began with the same basic ingredient, mustard seeds. But local history, food, and taste turned that ingredient into something completely different. And that's one of the most interesting things about mustard in Germany. There isn't one single German mustard that represents the whole country. Instead, different regions developed their own traditions. In Düsseldorf, mustard became known for its strength and sharpness. In Bavaria, it became famous for sweetness. Two regions, two very different flavors. One ancient seed. And that regional difference is exactly what makes the history of mustard so much more interesting than it first appears. Empires fell, wars changed borders, and trade routes came and went. But mustard stayed popular. Then industrialization changed how it was made. Instead of grinding seeds by hand, factories could produce thousands of jars at once and send mustard all over the world. The process became faster, but the basic idea stayed the same. Crushed mustard seeds, liquid, and time. Today, mustard is so common that most people barely think about it. It goes with hot dogs, pretzels, sandwiches, and countless other foods. Thousands of years after that ancient seed first found its way into European kitchens, its story is still being shaped by the places that embraced it. Düsseldorf kept the heat. Bavaria added sugar. The same seed became two regional identities.
