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 yolk
- Its fats and emulsifiers bind the oil or butter into a smooth, thick dressing.
- Mustard
- Adds sharp flavor and helps stabilize the emulsion.
- Oil or melted butter
- Provides fat that gives the dressing body and a rich mouthfeel.
- Vinegar or lemon juice
- Adds acidity that brightens flavor and thins the dressing to the desired consistency.
The step that matters
Add the oil or melted butter slowly while mixing. Adding fat gradually lets the egg yolk emulsify it evenly. Adding it too fast can cause the mixture to break and separate into greasy layers.
Swap the mustard
How well each one fits the dish's main ingredients (egg, butter, vinegar):

Fit is the average pairing score against egg, butter, vinegar. Candidates are from the same food group and used in at least 100 recipes.
