Mayonnaise originated in France in the 18th century but became a staple in American kitchens in the early 20th century, especially after commercial brands made it widely available. It is now a foundational condiment for sandwiches, salads, and countless American dishes.

In the U.S., variations include adding garlic for aioli, chipotle for a smoky kick, or dill for a classic dill mayo used on fish sandwiches. Some Southern recipes incorporate a touch of hot sauce or mustard for extra tang.

It is commonly served as a spread on sandwiches, a base for potato or Waldorf salads, and as a dip for fries or vegetables. It also serves as the foundation for many dressings and sauces.

Mayonnaise is a key ingredient in holiday dishes like potato salad for picnics, Waldorf salad for Thanksgiving, and deviled eggs for Easter brunches. It also appears in everyday family meals.

This recipe uses whole eggs and mustard as natural emulsifiers, giving a richer texture and fresher flavor. You can control the amount of sugar, salt, and add custom flavors, unlike many commercial mayos that contain preservatives and added sugars.

Common errors include adding oil too quickly, using cold eggs, or over‑blending which can cause the emulsion to break. Always add oil slowly while the blender runs and keep ingredients at room temperature.

Mustard contains natural lecithin and acidity, which help bind the oil and water phases more reliably, especially when using whole eggs. It also adds a subtle flavor that balances the richness of the oil.

Yes, store the finished mayo in an airtight jar in the refrigerator for up to 7 days. Keep it chilled and never leave it at room temperature for more than two hours to prevent bacterial growth.

The mayo should be thick, glossy, and smooth, holding its shape when lifted with a spoon. It should not appear watery or separated; if it does, gently blend in a little water or acid to rescue it.
