    Shared aroma: acetic acid (sour, vinegar).

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

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks
Lecithin in the yolks holds the oil and water-based liquids together as an emulsion.
Olive oil
Forms the bulk of the sauce, providing richness and a thick, creamy body when emulsified.
Vinegar
Adds acidity that balances the richness of the oil and helps stabilise the emulsion.

The step that matters

Adding the oil gradually. Oil must be added slowly while stirring so that small droplets disperse and are coated by yolk lecithin. Adding it too fast overwhelms the yolks, and the mixture breaks into a greasy, separated sauce.
