When making mayonnaise from scratch for special recipes, use only the best olive oil. The taste difference is astounding.
Mayonnaise is a standard favorite along with mustard for sandwich spreads. It is also one of the most-used ingredients for sauce and dip bases, especially in French cuisine.

While there is argument about its exact origins, there is no doubt about its flavorful addition to a wide range of foods.

Many cooks choose to make mayonnaise from scratch. It is a simple process that typically combines egg yolks and vinegar. Often, mustard and olive oil or lemon juice are added. The process must be precise for the ingredients to emulsify, whether in a blender or whipped by hand.


True mayonnaise contains approximately 70% - 80% fat, which may be a drawback for some diets. Flavored versions are gaining popularity.

Reduced fat or fat-free versions and salad dressings are a healthful alternative. These are not classified as the “real thing,” as they do not contain egg yolks.

Buying Tips

Always check the “use by” date. However, the shelf life can usually extend beyond that. Depending on use, you’ll have choices among glass, plastic, and squeeze containers.

Storage Tips

Always refrigerate opened jars. They should remain stable for about six months.
Commercial mayonnaise can indeed remain at room temperature for some time without danger of bacterial growth, but it may lose flavor.
Freezer or extremely cold temperatures will cause separation and an unpleasant change in texture.
Homemade mayonnaise will last four days, at most, in the refrigerator.

Other ingredients can include chopped anchovies, chipotle, or pureed asparagus.

1 cup sour cream
1/2 cup yogurt and ½
