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.
Slowly add a few drops of oil at a time while continuing to beat until the mixture becomes very thick.
Once thick, add the oil more rapidly, and when it gets hard to beat, add a little vinegar.
Continue adding the remaining oil and vinegar until the mixture is 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 into the mixture, creating a thick, stable dressing body.
- Oil
- Provides fat and richness, forming the bulk of the thick dressing.
- Vinegar
- Adds acidity that brightens the dressing and helps keep the emulsion stable.
- Whipped cream
- Adds lightness and a softer, creamier texture to the finished dressing.
- Mustard
- Its natural emulsifiers help hold the oil and egg yolk mixture together.
The step that matters
Adding the oil. Oil must be added a few drops at a time at first, while beating constantly. Adding it too fast before the yolks have absorbed it can break the emulsion, leaving a thin, separated dressing.
