Why it works: Olive and lemon are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 11,922 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Mayonnaise Dressing
Ingredients
Directions
Prepare
Chill utensils and ingredients thoroughly.
Make the mayonnaise
In a bowl, beat the egg yolks until creamy.
Add salt, sugar, and dry lemon juice; beat again.
Slowly add the olive oil while continuing to beat until thickened.
If the mixture becomes too thick, add 1 tablespoon of lemon juice or vinegar.
Continue adding oil and alternating with lemon juice or vinegar until fully combined.
Finish
For improved flavor, fold in 1 cup of whipped cream just before serving.

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 so the sauce thickens and holds together.
- Olive oil
- Provides the fat that forms the body and richness of the sauce.
- Vinegar
- Adds acidity that balances the richness and helps keep the emulsion stable.
- Whipped cream (in the method)
- Adds lightness and a softer, creamier texture to the finished dressing.
The step that matters
Adding the oil slowly while beating. Oil must be dispersed into tiny droplets among the egg yolk proteins to form an emulsion. Adding it too fast overwhelms the yolks, so the mixture breaks and fails to thicken.
Swap the lemon
How well each one fits the dish's main ingredients (egg, sugar, olive, vinegar):
- Lemonthe original
- Vanillafits about as well
- Cherryfits about as well
- Figfits about as well
Fit is the average pairing score against egg, sugar, olive, vinegar. Candidates are from the same food group and used in at least 100 recipes.
