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
- English mustard
- Adds sharp flavor and helps oil and vinegar stay blended as an emulsifier.
- Salad oil
- Provides fat that gives the dressing a smooth, rich body.
- White sugar
- Sweetness that balances the sharpness of the mustard and vinegar.
- Vinegar
- Adds acidity that brightens the flavor and thins the mixture.
The step that matters
Beat vigorously at the end. Oil and vinegar separate unless beaten into tiny droplets. Vigorous mixing disperses the oil so mustard can hold it in suspension, giving a smooth, stable consistency instead of a greasy, split dressing.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, pepper, vinegar):
- Capsicumfits better
- Mustardthe original
- Cabbagefits less well
- Cucumberfits less well
Fit is the average pairing score against sugar, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
