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 ↓
Rich Salad Dressing
Ingredients
Directions
Make the dressing
In a bowl, beat the egg yolks, mustard, sugar, cayenne pepper, and salt until very light and thick using a wooden spoon or a Dover beater.
Gradually add a few drops of oil at a time until the mixture becomes very thick. Once thick, you can add the oil more rapidly.
When the mixture is so thick that the beater turns hard, add a little vinegar.
After adding all the oil and vinegar, the dressing should be very thick.
Stir in the lemon juice and whipped cream.
Chill and serve
Chill in the refrigerator for a few hours before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil and vinegar, giving the dressing its thick, creamy body.
- Oil
- Forms the bulk of the dressing, providing richness and body once emulsified.
- Mustard
- Helps stabilise the emulsion so the oil stays dispersed in the dressing.
- Vinegar
- Adds acidity that balances the richness of the oil and yolks.
- Whipped cream
- Adds lightness and extra creaminess to the finished dressing.
- Sugar
- Adds sweetness that balances the acidity of the vinegar and lemon.
The step that matters
Add the oil slowly at the start. Egg yolks can only hold oil in a stable emulsion if it is added gradually while beating. Adding too much oil early causes the mixture to split and become oily instead of thick.
