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 ↓
Salad Dressing
Ingredients
Directions
Make the dressing
In a bowl, beat the egg yolks, mustard, sugar, salt, and red pepper until very light.
Gradually add the salad oil, mixing until the dressing thickens.
Thin the mixture with vinegar, then continue adding oil more rapidly.
To prevent curdling, add salt only after the dressing is made.
Finish and serve
For an improvement, fold in whipped cream just before serving.
You can substitute lemon juice for vinegar if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raw egg yolks
- Act as an emulsifier, holding the oil and vinegar together in a smooth, thick dressing.
- Salad oil
- Supplies the fat that gives the dressing its body and richness.
- Mustard
- Helps stabilise the emulsion so the oil stays dispersed in the dressing.
- Vinegar
- Adds acidity that brightens the flavour and thins the mixture.
The step that matters
Add the oil gradually while mixing. Oil must be dispersed into tiny droplets held by the egg yolk emulsifier. Adding oil too quickly overwhelms the yolks, so the dressing fails to thicken and may separate or curdle.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
