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 into the mixture and give the mayonnaise its thick, creamy structure.
- Salad oil
- Forms the bulk of the emulsion, giving the mayonnaise its rich fat content and smooth texture.
- Vinegar
- Adds acidity that sharpens the flavour and helps keep the emulsion stable.
The step that matters
Slowly add the oil while stirring. Oil must be added gradually so droplets are dispersed and surrounded by egg yolk lecithin. Adding it too fast can break the emulsion, leaving oil separated and the sauce thin or greasy.
