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 ↓

Ingredients
Directions
Prepare the eggs
Boil the eggs for 20 minutes.
Cut the eggs in half lengthwise and remove the yolks.
Make the filling
Mash the yolks and mix in melted butter, salt, mustard, and enough vinegar to moisten.

Assemble
Place one ball in each egg white half or fill the whites evenly and reassemble.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the main body of the salad, with yolks mashed into a rich filling and whites as the holder.
- Melted butter
- Adds fat and richness, giving the mashed yolk filling a smoother, softer texture.
- Prepared mustard
- Adds sharpness and aroma that balances the richness of the yolks and butter.
- Vinegar
- Adds acidity and moisture, loosening the mashed yolks and brightening the flavor.
The step that matters
Mash the yolks and add vinegar gradually. Yolks mixed with fat and liquid can turn dry or greasy if the liquid is off. Adding vinegar only until the mixture is moist keeps the filling smooth and spreadable rather than wet or crumbly.
Swap the mustard
How well each one fits the dish's main ingredients (egg, butter, vinegar, ham):
- Mustardthe original
- Shallotfits about as well
- Asparagusfits less well
- Cucumberfits less well
Fit is the average pairing score against egg, butter, vinegar, ham. Candidates are from the same food group and used in at least 100 recipes.
