Why it works: Vinegar and mustard 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 ↓
Ideal Olive Oil Mayonnaise
Ingredients
Directions
Make the mayonnaise
Place the egg yolks in a chilled bowl and set it in a pan of salted cracked ice.
Using a silver fork or tablespoon, begin to whip the yolks, adding the olive oil a drop at a time.
Continue to beat in this manner until about 2 tablespoons of oil have been added.
Then alternate adding the oil and vinegar, a teaspoon at a time, until all the vinegar and lemon juice are incorporated.
Continue to beat and add the remaining olive oil until the mixture is very stiff.
Blend the salt and mustard, then whip into the mayonnaise at the end.
Chill and store
Store in the coldest part of the refrigerator until serving.
If it separates, chill and whip briskly to thicken again.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsifiers that hold the oil and vinegar together in a stable, thick mixture.
- Olive oil
- Provides the fat that, dispersed into droplets, builds the rich, stiff body of the mayonnaise.
- White vinegar
- Adds acidity that brightens flavour and helps keep the emulsion stable.
- Lemon juice
- Adds acidity and fresh flavour that balances the richness of the oil.
The step that matters
Adding the oil slowly at the start. Egg yolk can only emulsify a limited amount of oil at first. Adding oil a drop at a time lets each droplet be coated before more is added. Too much oil too early causes the mixture to separate and break.
Swap the lemon
How well each one fits the dish's main ingredients (egg, olive, vinegar, mustard):
- Avocadofits better
- Lemonthe original
- Cherryfits about as well
- Limefits about as well
Fit is the average pairing score against egg, olive, vinegar, mustard. Candidates are from the same food group and used in at least 100 recipes.
