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 emulsion
In a bowl, beat the egg yolks, mustard, sugar, cayenne, and salt until very light and thick.
Set the bowl in a pan of ice water while beating.
Slowly add a few drops of oil at a time until the mixture becomes very thick.
Once thick, add the oil more rapidly.
If the mixture becomes too thick for the beater, add a little vinegar.
After adding all the oil and vinegar, the mixture should be very thick.
Finish and chill
Stir in the lemon juice and whipped cream, then refrigerate for a few hours before using.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Their lecithin emulsifies the oil and water, holding the dressing together and giving it body.
- Oil
- Forms the bulk of the dressing, creating a rich, thick texture when emulsified into the yolks.
- Mustard
- Acts as a secondary emulsifier that helps keep the oil and yolk mixture stable.
- Vinegar
- Thins the mixture when it gets too stiff and adds sharp acidity to balance the richness.
- Whipped cream
- Adds lightness and a softer, creamier mouthfeel to the finished dressing.
The step that matters
Adding the oil slowly at the start. Egg yolks can only hold a limited amount of oil at first. Adding oil in drops while beating lets the emulsion form; adding it too fast causes it to break and turn runny and greasy.
