Why it works: Mustard and vinegar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Mayonnaise Dressing
Ingredients
Directions
Make the dressing
Combine one-half teaspoonful of mustard, one-half teaspoonful of sugar, one teaspoonful of salt, and a dash of cayenne pepper.
Add two raw egg yolks and beat well.
Stir in one teaspoonful of strong vinegar.
Add very carefully, drop by drop, a scant three-quarters of a cup of best olive oil, and as it thickens add half a teaspoonful of vinegar.
Keep it cold
Keep the eggs and oil refrigerated and ice cold.
Optionally use lemon juice instead of vinegar if preferred.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil into the vinegar, giving the dressing its thick, creamy body.
- Olive oil
- Provides the fat that forms the body and rich texture of the dressing.
- Vinegar
- Adds acidity that balances the richness of the oil and egg yolks.
- Mustard
- Helps stabilize the emulsion so the oil stays suspended in the dressing.
The step that matters
Adding the oil. Oil must be added very slowly, drop by drop at first, so the egg yolk can disperse it into tiny droplets. Adding it too fast breaks the emulsion, and the dressing separates into a greasy, runny mixture. Cold eggs and oil also help the emulsion hold.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, pepper, vinegar, olive, egg):
- Capsicumfits better
- Mustardthe original
- Cucumberfits about as well
- Tomatofits less well
Fit is the average pairing score against sugar, pepper, vinegar, olive, egg. Candidates are from the same food group and used in at least 100 recipes.
