What is mayo and mustard mixed together called?

Mayonnaise and mustard are two popular condiments that both have their place in the refrigerator. While they have distinctly different flavors on their own, some people enjoy combining mayo and mustard to create a tasty hybrid condiment. But what exactly do you call this zesty mixture of mayo and mustard?

The Origin of Mayonnaise

Mayonnaise is a thick, creamy sauce or dressing that is made by emulsifying egg yolks and oil, usually with some acidic ingredients like lemon juice or vinegar added. It has a rich, tangy flavor and smooth, spreadable texture.

The origins of modern mayonnaise can be traced back to the early 18th century in France. According to the historical record, it was first made by the chef of the Duc de Richelieu in 1756. The chef decided to make a celebratory sauce for the duke and his army officers after their successful invasion of the island of Minorca off the Mediterranean coast of Spain. The chef based this new sauce on a popular sauce called “aioli” that was made in the Provence region of France at the time, which contained garlic, olive oil, and egg yolks.

The chef omitted the garlic and added some vinegar or lemon juice to the egg yolk and olive oil mixture, creating a lighter, subtly flavored sauce that was intended to highlight the food instead of overpowering it. He named this new sauce “mahonnaise” after the city of Mahón, which was the capital of Minorca. Over time, the name evolved into “mayonnaise.”

The cool, creamy taste and versatility of mayonnaise caused it to rapidly increase in popularity in France and later throughout Europe and globally. While the original recipe has been tweaked and commercialized over the centuries, the basic formula of egg yolk, oil, vinegar or lemon, and seasonings remains the foundation of all mayonnaise today.

The History of Mustard

Mustard is a condiment made from the seeds of the mustard plant, which are ground up and mixed with liquid to create a thick, spicy paste. It has been used for thousands of years and has roots in many cultures around the world.

The earliest written records of mustard date back to ancient Roman and Greek texts from around 300 B.C. Ground mustard seeds were likely being mixed with wine or grape juice to make the spicy, tangy condiment we now know as mustard. It was likely brought to Europe by the Romans from its origins in Northern Africa and the Mediterranean.

In the 18th century, it became very popular in France to mix ground mustard seeds with verjuice, an acidic juice made from unripe grapes. This French-style mustard became well-regarded and helped increase mustard’s popularity across Europe.

In 1814, the first ready-made mustard was sold by Jeremiah Colman in England. He made a paste of mustard flour and water called Colman’s Mustard, which set the standard for commercially prepared mustards. The bright yellow color and milder flavor of Colman’s mustard increased the condiment’s appeal.

Today, mustard is used in cuisine around the world to add flavor and spice. The most popular varieties like Dijon mustard from France, whole grain mustard, and yellow mustard are still made using processes similar to Jeremiah Colman’s original formula with the addition of some modern innovations.

Combining Mayo and Mustard

With their rich histories and complementary flavors, it’s no wonder that people started blending mayonnaise and mustard together. Combining the creaminess of mayo with the spicy tang of mustard results in a flavorful hybrid condiment.

There are a few key benefits that make mayo and mustard work well together:

  • Mayonnaise helps mellow out the sharpness of mustard, while still allowing its flavor to come through.
  • Mustard brings a zesty, spicy kick to the rich smoothness of mayonnaise.
  • When blended together, the texture becomes creamier and more spreadable.
  • The egg yolks and oils in mayo nicely emulsify the mustard paste.
  • The acidity levels balance each other out.

The combination of mayo and mustard can transform from a salad dressing binder to a flavorful sandwich spread or veggie dip depending on how much of each condiment is added. Recipes typically call for 1 part mustard to 3 or 4 parts mayo, but the proportions can be adjusted to suit individual tastes.
