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
Make the dressing
Combine one teaspoonful of mustard, one teaspoonful of powdered sugar, one-half teaspoonful of salt, a pinch of cayenne pepper, yolks of two raw eggs, one pint of olive oil, two tablespoonfuls of vinegar, and two tablespoonfuls of lemon juice; mix the first.
In a small bowl, add the eggs and stir well.
Add the oil a few drops at a time, stirring constantly with a fork until it thickens.
Do not try to stir it all in at once, but very gradually.
When the dressing becomes thick, thin it with a little lemon; then add more oil and lemon alternately, and lastly add the vinegar.
If the egg does not thicken quickly, add one-half teaspoonful of the unbeaten white of an egg or a few drops of vinegar to help it thicken and keep it smooth.
Finish and serve
Just before using it, add one-half cupful of whipped cream.
Never mix the mayonnaise dressing with the meat or fish until ready to serve, and then leave half of it to pour over the top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks emulsify with the oil to form the thick dressing structure.
- Olive oil
- Forms the bulk of the emulsion, giving the dressing its richness and body.
- Mustard
- Helps stabilise the emulsion so the oil and egg stay combined.
- Vinegar
- Adds acidity that brightens the flavour and balances the richness of the oil.
- Whipped cream
- Adds lightness and softness to the finished dressing just before serving.
The step that matters
Adding the oil. Oil must be added very slowly while stirring constantly, because the egg yolk can only hold tiny droplets at first. Adding too much oil at once breaks the emulsion, leaving the dressing thin and separated.
