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 dressing
Beat the egg yolks, mustard, sugar, salt, and cayenne in a bowl until very light and thick.
Add the oil drop by drop until the mixture thickens and cannot be stirred.
Add the oil a little faster until it becomes stiff again.
Alternately add the vinegar and remaining oil.
Add the lemon juice and whipped cream if desired.
Chill or serve
Chill in the refrigerator for a few hours or serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsifier that holds the oil and vinegar together as a thick, smooth dressing.
- Salad oil
- Supplies the fat that gives the dressing its rich body and texture.
- Vinegar
- Adds acidity for sharp flavor and helps keep the emulsion stable.
- Dry mustard
- Helps stabilize the emulsion and adds a sharp, pungent flavor.
The step that matters
Adding the oil slowly at the start. Oil must be added drop by drop while beating, so the yolks can coat each droplet. Adding it too fast breaks the emulsion, leaving a thin, separated mixture that will not thicken.
“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.
