Why it works: Lemon and pepper 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
Pack a bowl in a larger bowl filled with cracked ice.
In a smaller bowl, sift together salt and cayenne.
Add egg yolks and stir until well mixed.
Add 1½ teaspoons lemon juice.
Make the mayonnaise
Slowly add the first ¼ cup of oil, drop by drop, stirring constantly.
As the mixture thickens, alternate adding 1 teaspoon of vinegar or lemon juice with the oil.
Once the first ¼ cup of oil is incorporated, the mixture should be the consistency of boiled custard.
Continue adding oil in larger quantities, beating constantly, alternating with vinegar and lemon juice until all are used.
If the dressing curdles, add another yolk to a chilled bowl and slowly beat in the curdled mixture.
Keep all ingredients thoroughly chilled and use a small wooden spoon for the first ¼ cup of oil; finish with a Dover egg beater.
The mayonnaise should be stiff enough to hold its shape and should be kept cold.

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 lemon juice into a stable, thick dressing.
- Olive oil
- Forms the bulk of the dressing, providing richness and body as it is emulsified.
- Lemon juice
- Adds acidity that brightens flavour and helps the emulsion thicken.
- Vinegar
- Adds acidity that brightens flavour and helps the emulsion thicken.
The step that matters
Adding the first oil slowly. Oil must be dispersed into the yolks in tiny droplets while stirring constantly. Adding it too fast overwhelms the yolk lecithin, so the emulsion breaks and the mayonnaise curdles.
