Ketchup, Mustard and Mayonnaise: Sauces as Condiments

When you think of ketchup, mustard and mayonnaise, you probably think of them as condiments. They are used for flavor not for nutrition. However, these sauces can be used as a substitution for fat in a healthy diet. Ketchup, mustard and mayonnaise are similar in that they contain vinegar, oil or vegetable oil, and often seasonings like garlic, onion, mustard seed, and spices such as salt and sugar. Ketchup and mustard are both made with a base of vinegar and sugar, while mayonnaise is made with an egg yolk, vegetable oil and vinegar. Ketchup is used as a condiment made from tomato sauce, vinegar, sugar, spices and sometimes cornstarch. Mustard is made from mustard seed, spices, water and sometimes vinegar. Mayonnaise is made from egg yolk, vegetable oil, vinegar, and sometimes flavoring.

How is Ketchup Made?

Tomato ketchup is made by fermenting tomato skins. The resulting "must" is then boiled with sugar, pectin, and spices. Other ingredients including apple cider vinegar, onions, garlic, and carrots can be added to give the ketchup its distinctive flavour. Must is a fermented beverage made from the lees (sediment) and skin of the fruits or vegetables used to produce the must. For example, grape skin is fermented to produce red wine, pear skin is fermented to produce sherry, and apple is fermented to produce apple cider or apple juice. Fermentation is the process of converting sugars into alcohol and carbon dioxide, either naturally or by adding microbes. While it is possible to make ketchup without fermentation, it takes much longer and tastes markedly different from the traditional sauce.

In addition to added sugar, most ketchup brands have added synthetic vitamins and synthetic colours. You could make ketchup at home by sautéing tomatoes in a healthy oil with onions, bell peppers and herbs.

How is Mustard Made?

Mustard is a condiment made from the seeds of the mustard plant. The most common type of mustard is yellow mustard, which is made from a mix of seeds of the "breeds" S Dancer, V Cineraria, and Mutant. However you can also find other varieties like black mustard, brown mustard, and white mustard. Yellow mustard is made from the seeds of all three types of mustard, along with other spices. Mustard is conventionally made with water, vinegar, mustard seeds, and spices like salt, garlic, and sometimes sugar.

How to make Mayonnaise

Mayonnaise is a type of salad dressing made by whisking together oil with egg yolks, vinegar, herbs, mustard, and spices. Common ingredients include oil, water, salt, mustard, lemon, and egg yolks. Dry mustard is sometimes used, but fresh is best. Avoid cheap brands as they often contain cheap and unnecessary additives. Water is added to the mayonnaise to make it thinner. Vinegar, like ketchup and mustard, is a source of possible acidity, but it is a vital component of making mayonnaise.

Are they Sauces or Condiments?

All three of these sauces are made from vinegar, sugar, and spices. However, in each one, there are different spices and different amounts of sugar. Ketchup, mustard and mayonnaise are all made from a base of vinegar and sugar. When you make ketchup, you are making a sauce, not a condiment. When you make mustard, you are making a condiment, not a sauce. And when you make mayonnaise, you are making a salad dressing, not a condiment. When labels say "sauces," they usually mean "non-condiments," such as mustard, sauces, and mayonnaise. However, if you are looking for a "condiment," "ketchup," "mustard," or "mayonnaise," is usually still fine on the label.


The most important thing to remember when you want to start making your own ketchup or mustard is that it can be done. It may take a little time and effort (not to mention some experimenting), but once you get the hang of it, it will be well worth it. And, if you don't like it, you can always make another batch with a few adjustments.
