Egg and vinegar barely smell alike, yet cooks put them together in 12,922 recipes: they work on texture and structure more than aroma.

What each ingredient does

Egg yolks
Their lecithin emulsifies the oil into droplets, forming a stable, thick sauce.
Finest salad oil
Supplies the fat that gives mayonnaise its rich body and smooth texture.
Vinegar
Adds acidity that balances the richness and sharpens the flavour.

The step that matters

Adding the oil drop by drop. Oil added too fast cannot be dispersed into the yolk, so the emulsion breaks and the sauce stays runny and separated. Slow addition with constant mixing lets each droplet get coated by yolk proteins and lecithin, building a stable emulsion.
