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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Lecithin in the yolks lets the oil and cream blend into a stable, thick emulsion.
- Oil
- Provides fat that gives the dressing body, richness and a smooth mouthfeel.
- Cream
- Adds fat and moisture, softening the dressing and making it creamier.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness of the fats.
- Dry mustard
- Helps stabilise the emulsion and adds a sharp, pungent flavour.
- Castor sugar
- Adds a little sweetness that rounds out the sharpness of the vinegar.
The step that matters
Adding the raw yolks and oil and cream gradually. Egg yolk emulsifies oil into tiny droplets suspended in the cream. If the oil is added too quickly, the droplets merge and the dressing can split or look greasy instead of thick and smooth.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, pepper, cream, vinegar):
- Capsicumfits about as well
- Mustardthe original
- Horseradishfits about as well
- Spinachfits less well
Fit is the average pairing score against egg, sugar, pepper, cream, vinegar. Candidates are from the same food group and used in at least 100 recipes.
