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 base
In a small bowl, mix mustard, powdered sugar, coarse sea salt, and cayenne pepper.
Add the egg yolks and stir well.
Emulsify the dressing
Gradually add the olive oil, a few drops at a time, stirring constantly with a fork until thickened.
Once thick, thin the dressing with a little lemon juice, then alternate adding more oil and lemon juice.
Finally, add the vinegar.
If the dressing does not thicken quickly, add ½ teaspoon unbeaten egg white or a few drops of vinegar to help smooth it out.
Finish and serve
Just before serving, fold in the whipped cream.
Do not mix the mayonnaise dressing with meat or fish until ready to serve, reserving half 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
- Egg yolks
- Emulsifiers that bind the oil and water so the dressing thickens and stays smooth.
- Olive oil
- Supplies the fat that, dispersed into droplets, builds the thick body of the dressing.
- Mustard
- Helps stabilise the emulsion so the oil stays dispersed instead of separating.
- Lemon juice
- Adds acidity for brightness and helps thin the dressing to a workable consistency.
- Whipped cream
- Adds lightness and a softer, airier texture when folded in at the end.
The step that matters
Adding the oil gradually. Oil must be added a few drops at a time while whisking constantly so it disperses into tiny droplets held by the egg yolk. Adding it too fast overwhelms the yolk, and the emulsion breaks into a greasy, runny mixture.
Swap the lemon
How well each one fits the dish's main ingredients (mustard, sugar, pepper, egg, olive, vinegar, cream):

- Limefits less well
Fit is the average pairing score against mustard, sugar, pepper, egg, olive, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
