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 ↓
Mayonnaise Dressing
Ingredients
Directions
Prepare the yolks
Boil 3 eggs hard and let them cool.
Remove the yolks and pass them through a sieve.
Make the dressing
In a bowl, combine the sieved yolks with the 3 raw yolks, salt, and Cayenne pepper.
Beat the mixture until very light.
Slowly add the oil while occasionally adding a little vinegar or lemon juice to taste.

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
- Eggs
- Yolks act as an emulsifier, holding the oil and acid together in a smooth, thick dressing.
- Oil
- Provides fat for richness and body, forming the bulk of the thick dressing.
- Vinegar or lemon juice
- Adds acidity that brightens the dressing and balances the richness of the oil.
The step that matters
Slowly add the oil. Oil must be dispersed into tiny droplets among the yolks to form a stable emulsion. Adding it too quickly overwhelms the yolks, so the dressing can split and become oily and loose.
