Why it works: Pepper and vinegar are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 27,814 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Mayonnaise for Salad
Ingredients
Directions
Make the emulsion
Combine the egg yolk, salt, white pepper, cayenne pepper, and vinegar in a bowl until smooth.
Gradually add the salad oil, starting with 2-3 drops at a time, mixing until a thick paste forms.
Add a little vinegar to achieve a consistency similar to rich cream.
Continue alternating between adding oil and vinegar, stirring constantly, until all the oil and vinegar are used.
Rescue and store
If the mayonnaise curdles, chill it in the refrigerator for 30 minutes, then finish mixing.
Keep the mayonnaise in a cold place until ready to serve.

Egg and vinegar barely smell alike, yet cooks put them together in 12,922 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Lecithin in the yolk emulsifies the oil and vinegar into a stable, thick sauce.
- Salad oil
- Forms the bulk of the sauce, giving it richness and a thick, creamy body.
- Vinegar
- Adds acidity that balances the rich oil and helps thin the emulsion to a creamy consistency.
The step that matters
Adding the oil slowly at the start. The yolk can only hold a small amount of oil at first. Adding oil in drops while mixing lets the droplets be coated and dispersed; adding it too fast breaks the emulsion, so it curdles and separates.
Swap the white pepper
How well each one fits the dish's main ingredients (egg, pepper, vinegar):
- Tarragonfits better
- Dillfits better
- Parsleyfits better
- White pepperthe original
Fit is the average pairing score against egg, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
