Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Mayonnaise Dressing
Ingredients
Directions
Prepare the base
Pass the hard-boiled egg yolks through a sieve.
Add salt, mustard, and cayenne pepper to the yolks.
Cream the butter and mix in the raw egg yolks and the hard-boiled mixture.
In three separate cups, have the oil, vinegar, and lemon juice ready.
Make the dressing
Add 1 teaspoon of oil, then 1 teaspoon of lemon juice, followed by vinegar, and continue alternating until all ingredients are used.
Beat the mixture with a Dover egg beater, stirring in one direction.
Taste frequently to ensure it doesn't become too sour.

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 butter into a thick, smooth dressing.
- Butter
- Adds richness and a creamy, smooth texture to the dressing.
- Oil
- Forms the bulk of the emulsion, giving body and a silky texture.
- Vinegar
- Adds sharpness that balances the richness of the oil and yolks.
- Lemon juice
- Adds acidity and brightness that balances the fat.
The step that matters
Adding the oil and acid slowly while beating. Oil must be added gradually while beating so it disperses into tiny droplets held by the egg yolk lecithin. Adding it too fast breaks the emulsion, leaving the dressing oily and separated.
Swap the mustard
