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 ↓
Deviled Eggs
Ingredients
Directions
Prepare the filling
Cut the eggs in half lengthwise.
Remove the yolks and mash them.
Mix the yolks with mustard, salt, vinegar, and pepper, and beat until light.
Fill and serve
Heap each half white neatly with the mixture.
If packing for a picnic, fill the whites level full and fold together in pairs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Form the creamy base of the filling once mashed and beaten with the other seasonings.
- Vinegar
- Adds acidity that brightens the flavour of the rich yolk filling.
- Mixed mustard
- Adds sharp, pungent flavour that balances the richness of the yolks.
The step that matters
Beat the yolk mixture until light. Beating the mashed yolks with the vinegar and seasonings makes the filling smooth and airy, so it spreads evenly and holds its shape when heaped into the whites.
Swap the mustard
How well each one fits the dish's main ingredients (egg, vinegar, pepper):
- Capsicumfits better
- Mustardthe original
- Cucumberfits about as well
- Cabbagefits less well
Fit is the average pairing score against egg, vinegar, pepper. Candidates are from the same food group and used in at least 100 recipes.
