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 base
Place the uncooked yolks of two eggs into a cold soup dish.
Beat the yolks well with a silver or wooden fork for one minute.
Add half a teaspoon of salt, a dash of cayenne pepper, and, if desired, half a teaspoon of mustard.
Whisk the mixture well.
Add the oil
Slowly drizzle in half a pint or more of olive oil, drop by drop.
Stir rapidly and steadily while adding the oil, avoiding reverse motion to prevent curdling.
After adding one gill of oil, alternate occasionally with a few drops of lemon juice or vinegar until a proper consistency is reached.
Add more or less oil as needed to achieve the desired quantity of dressing.
(Optional) If using a quart bottle of oil, stir it into the yolks after adding the first gill of oil, alternating with a few drops of lemon juice or vinegar.
Finish by adding more oil as directed.
Rescue and store
If the dressing curdles, start over with the yolks of two eggs in another plate.
Stir the yolks well, then gradually add the curdled mayonnaise, stirring continuously.
In warm weather, place the dressing vessel on a piece of ice or in a pan of cold water to keep the oil and eggs very cold.
Keep the dressing covered and stored in the ice for up to a week.
Optionally, use tarragon vinegar instead of regular vinegar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsifier that binds the oil and lemon juice or vinegar into a stable, thick dressing.
- Oil
- Forms the body and rich texture of the dressing as it is slowly emulsified into the yolks.
- Lemon juice or vinegar
- Adds acidity that brightens flavor and helps the emulsion reach a proper consistency.
- Mustard
- Helps stabilize the emulsion and adds a sharp, savory flavor.
The step that matters
Adding the oil slowly while stirring steadily. Oil must be dispersed in tiny droplets so the yolk lecithin can coat them. Adding it too fast or stirring backward can break the emulsion, causing the dressing to curdle.
Swap the mustard

- Mustardthe original
Fit is the average pairing score against egg, pepper, lemon, vinegar. Candidates are from the same food group and used in at least 100 recipes.
