Why it works: Pepper and vinegar are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 27,814 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil and water, giving the sauce its thick, creamy structure.
- Oil
- Supplies the fat that, dispersed into droplets, gives the mayonnaise its body and richness.
- Vinegar
- Adds acidity that brightens flavour and helps stabilise the emulsion.
The step that matters
Gradually add the oil while whisking. Oil must be added slowly so it breaks into tiny droplets that the egg yolk lecithin can coat. Adding it too fast can cause the emulsion to break and the sauce to separate.
