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
- Cornstarch
- Thickens the dressing as it is heated, giving it body without eggs.
- Cream or milk
- Adds richness and a smooth, creamy body to the dressing.
- Vinegar
- Provides the acidity that gives the dressing its tang.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Butter
- Adds fat for mouthfeel and a rich flavor.
The step that matters
Thicken the dressing with cornstarch as needed. Cornstarch thickens only when heated and then held near a simmer, as its starch granules swell and gel. Adding it without heating leaves the dressing thin, while overheating can break the texture. Add it gradually and check consistency as it cooks.
Swap the mustard
How well each one fits the dish's main ingredients (butter, sugar, pepper, cream, vinegar):
- Capsicumfits about as well
- Mustardthe original
- Potatofits about as well
- Onionfits less well
Fit is the average pairing score against butter, sugar, pepper, cream, vinegar. Candidates are from the same food group and used in at least 100 recipes.
