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 ↓
Dressing for Cold-slaw

Make the sauce
Mix together the sugar, salt, mustard, and warm water until smooth.
Stir in the oil.
Heat the mixture over medium heat until it boils, stirring steadily.

Finish and cool
Add the vinegar and let it cool before using for slaw or cold meats.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the dressing as they set gently with the heat, giving it body.
- Dry mustard
- Adds sharp, pungent flavour that balances the sweetness and richness.
- Vinegar
- Adds acidity that brightens the dressing and balances its richness.
- Oil, cream, or melted butter
- Adds fat, giving the dressing a smoother, richer mouthfeel.
The step that matters
Return the sauce to the heat over boiling water and stir until smooth and thick. Eggs thicken when heated, but if they get too hot they can curdle or scramble. Gentle heat over boiling water and constant stirring keep the sauce smooth while it thickens.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, egg, vinegar, cream):
- Mustardthe original
- Cucumberfits about as well
- Capsicumfits about as well
- Horseradishfits about as well
Fit is the average pairing score against sugar, egg, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
