Why it works: Lemon and egg are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 44,316 recipes. Both carry (e,e)-2,4-decadienal, which smells fatty, deep fried. The science ↓
Mayonnaise Dressing
Ingredients
Directions
Make the base
Separate the yolks of 3 uncooked eggs. Add 1 teaspoon salt, 1 cup vinegar, and juice of 2 lemons.
Add 1 cup whipped cream and 1 pint oil or butter.
Beat the yolks and dry ingredients until very light, using a silver or wooden spoon, with the bowl set in a pan of ice water.
Emulsify and finish
Add a few drops of oil at a time until the dressing becomes very thick or nearly hard.
Add more oil rapidly, beating hard.
Add vinegar.
When the oil and vinegar are fully incorporated, the dressing should be very thick.
Add lemon juice and whipped cream.
Place the dressing on ice for a few hours.
The whipped cream may be omitted.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks emulsify with the oil to form a thick, stable dressing.
- Oil
- Forms the bulk of the dressing, giving richness and body as it emulsifies.
- Vinegar
- Adds acidity that balances the richness of the oil and yolks.
- Lemon juice
- Adds acidity and bright flavour that cuts through the fat.
- Whipped cream
- Adds lightness and softness to the finished dressing.
The step that matters
Adding the oil. Oil must be added slowly at first so the yolks can absorb it and form an emulsion. Adding it too fast can break the dressing into separated oil and liquid, so it fails to thicken.
Swap the lemon
