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 ↓
Devilled Eggs
Ingredients
Directions
Prepare
Boil the eggs for at least 15 minutes until hard.
Once cooled, cut the eggs in half and remove the yolks.
Trim a small slice off the bottom of each egg white so they can stand upright.
Fill and serve
In a bowl, mix the yolks with vinegar, pepper, salt, mustard, and melted butter until smooth.
Fill the egg whites with the yolk mixture and serve with cold tongue.

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.
- Vinegar
- Adds acidity that brightens the rich yolk filling.
- Mustard
- Adds sharp flavour that balances the richness of the yolks.
- Melted butter
- Adds fat that makes the yolk mixture smooth and creamy.
The step that matters
Mix the yolks until smooth. Melted butter must be fully blended into the yolks; if the mixture is lumpy or the butter is too hot, the filling can split or turn grainy and hard to pipe or spoon neatly.
Swap the mustard
How well each one fits the dish's main ingredients (egg, vinegar, pepper, butter):
- Capsicumfits better
- Mustardthe original
- Shallotfits about as well
- Cucumberfits about as well
Fit is the average pairing score against egg, vinegar, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
