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
- Whites provide the structure that holds the filling, and yolks supply the rich base of the filling.
- Salad oil
- Adds fat to the mashed yolks, making the filling smooth and creamy.
- Vinegar
- Adds acidity that brightens the rich yolk filling.
- Prepared mustard
- Adds sharp flavour and helps emulsify the yolk paste.
The step that matters
Mash the yolks into a paste. Yolks must be mashed thoroughly with the oil and vinegar so the emulsion becomes smooth; lumps of yolk stay dry and crumbly rather than creamy.
Swap the mustard
How well each one fits the dish's main ingredients (egg, vinegar, sauce):

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