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
- Eggs
- Thicken the dressing as they cook and add richness.
- Vinegar
- Provides the sharp acidity that defines the dressing.
- Butter
- Adds richness and a smooth, creamy mouthfeel.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Mustard
- Adds a sharp, pungent flavor.
The step that matters
Adding the eggs and reboiling. Egg proteins thicken the dressing by setting as they heat. If the mixture gets too hot or boils hard after the eggs go in, they scramble into lumps. Stirring constantly keeps the heat even and the dressing smooth.
Swap the mustard
How well each one fits the dish's main ingredients (vinegar, egg, sugar, butter, pepper):
- Capsicumfits better
- Mustardthe original
- Cucumberfits about as well
- Shallotfits less well
Fit is the average pairing score against vinegar, egg, sugar, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
