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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Mashed yolks emulsify with the cream and vinegar, giving the dressing a smooth, rich body.
- Vinegar
- Adds acidity that sharpens the flavour and balances the richness of the yolks and cream.
- Cream or milk
- Adds fat and liquid that thin the mixture and give it a creamy texture.
- Dry mustard
- Contributes sharp aroma and helps stabilise the emulsion.
- Castor sugar
- Adds sweetness that rounds out the acidity of the vinegar.
The step that matters
Gradually mix in the cream or milk. Adding liquid slowly lets the egg yolk particles disperse evenly, so the dressing becomes smooth instead of separating or turning lumpy.
Swap the mustard
How well each one fits the dish's main ingredients (egg, vinegar, sugar, cream):
- Mustardthe original
- Cucumberfits about as well
- Capsicumfits about as well
- Horseradishfits about as well
Fit is the average pairing score against egg, vinegar, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
