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
- Thicken the dressing and add richness as they set with gentle heat.
- Corn starch
- Thickens the liquid into a smooth, spreadable dressing when it boils.
- Vinegar
- Adds the sharp acidity that gives the dressing its tang.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Butter
- Adds fat for a smoother, richer mouthfeel.
- Cream
- Adds richness and softens the sharpness of the vinegar.
The step that matters
Boil the mixture after adding the vinegar. Corn starch only thickens fully once it reaches a boil, so the dressing stays thin if it is not brought up to boiling. Egg yolks can curdle if overheated, so keep the heat controlled while stirring.
Swap the mustard
How well each one fits the dish's main ingredients (egg, corn, sugar, butter, pepper, vinegar, cream):
- Capsicumfits better
- Potatofits about as well
- Mustardthe original
- Asparagusfits about as well
Fit is the average pairing score against egg, corn, sugar, butter, pepper, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
