Why it works: Lemon and pepper 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
Prepare the yolks
Separate the yolks carefully and place them in a mixing bowl.
Beat the yolks slightly using a mixer.
Make the dressing
Add the olive oil drop by drop while stirring steadily until half the oil is incorporated.
Alternate adding lemon juice and the remaining oil until well blended.
Season to taste, then pour into a pint jar, seal tightly, and refrigerate for up to two weeks.
To use, thin with whipped cream or beaten egg white if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks (in the method)
- Emulsifier that holds the oil and lemon juice together as a smooth, thick dressing.
- Olive oil
- Provides the fat that gives the dressing its rich body and mouthfeel.
- Lemon juice
- Adds acidity that brightens the flavor and balances the richness of the oil.
The step that matters
Adding the olive oil drop by drop. Oil must be dispersed into the yolks in tiny droplets while stirring steadily. Adding it too fast overwhelms the yolk emulsifier, so the mixture breaks and separates instead of thickening.
Swap the lemon
How well each one fits the dish's main ingredients (olive, pepper):
- Limefits about as well
- Lemonthe original
- Avocadofits less well
- Cherryfits less well
Fit is the average pairing score against olive, pepper. Candidates are from the same food group and used in at least 100 recipes.
