Glossary Term: Mayonnaise

Mayonnaise Definition:

Mayonnaise is a cold emulsified sauce made primarily from egg yolks, oil, mustard, and an acid such as vinegar or lemon juice. It has a thick, creamy texture, created by slowly whisking oil into the egg mixture. Mayonnaise is widely used as a condiment, base sauce, and ingredient in dressings, salads, and sandwiches. In professional kitchens, it is valued for its texture, stability, and versatility in both classic and modern cuisine.

Mayonnaise Key Concepts:

An Emulsion-Based Sauce: Mayonnaise relies on emulsification, in which oil and water-based ingredients are blended into a smooth, stable mixture.
Texture and Consistency: Properly made mayonnaise should be thick, glossy, and smooth without separating.
Cold Preparation Method: Unlike many sauces, mayonnaise is usually prepared without heat to maintain its creamy structure.
Foundation for Other Sauces: It is commonly used as a base for flavored sauces, dips, and dressings in culinary applications.
Balance of Fat and Acidity: The combination of oil and acid creates richness while preventing the sauce from tasting too heavy.

What It Does Not Mean

It is not Hollandaise Sauce; mayonnaise is a cold emulsion made with oil, while Hollandaise Sauce is a warm butter-based emulsion.
It is not Aioli; traditional Aioli is garlic-forward and may vary in ingredients and preparation by regional style.

Contextual Usage

“The chef prepared fresh mayonnaise for the sandwich station during prep work”.
“A stable mayonnaise showed the student had properly understood emulsification techniques”.
