Mayonnaise originated in the 18th‑century French port of Mahón and quickly became a staple in French households. It is traditionally served as a cold sauce accompanying salads, seafood, and as a base for many other French sauces.

In Provence, a touch of garlic is added to create a simple aioli. In the north, some cooks use a splash of white wine instead of vinegar. The core technique—egg yolk, oil, mustard, and acid—remains the same across regions.

It is typically served chilled as a condiment for boiled potatoes, green beans, or cold meats, and it also forms the base for sauces like sauce rémoulade and tartar sauce.

Mayonnaise appears on family picnics, summer barbecues, and holiday meals where cold salads and seafood platters are served. It is a everyday staple rather than a festive‑only sauce.

Authentic ingredients are egg yolk, Dijon mustard, white wine vinegar, fine sea salt, pepper, and a neutral oil such as grapeseed. Acceptable substitutes include lemon juice for vinegar, whole‑grain mustard for Dijon, and canola oil for grapeseed.

It pairs beautifully with boiled potatoes (pommes vapeur), green beans (haricots verts), smoked salmon, and as a base for sauce rémoulade served with fried fish or cold meats.

The biggest errors are adding oil too quickly, using cold egg yolk, and over‑whisking once the emulsion is set. All of these can cause the mayo to break or become grainy.

Dijon mustard provides a smooth texture and a subtle acidity that helps stabilize the emulsion without overpowering the delicate flavor of the sauce.

Yes, you can make it up to two days ahead. Store it in an airtight container in the refrigerator at 4 °C. Bring it to room temperature before serving and give it a quick whisk if it has thickened.

The mayo should be thick, glossy, and hold a spoon‑shape without dripping. It should have a pale ivory color; if it looks pale yellow, the mustard may be too light, but the texture is the key indicator.

When all the oil has been incorporated and the mixture has doubled in volume, becoming smooth, thick, and glossy, the mayonnaise is finished. It will not separate when the whisk is lifted.
