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 ↓
Devilled Eggs
Ingredients
Directions
Prepare the eggs
Boil the eggs hard and cool them in cold water.
Cut the eggs in half and slice a bit off the bottoms to make them stand upright.
Make the filling
Remove the yolks and mash them into a smooth paste with melted butter, cayenne pepper, mustard, and vinegar.
Fill the hollowed egg whites with the yolk mixture.
Serve
Serve on a bed of chopped cresses seasoned with salt, pepper, vinegar, and sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks provide the rich, creamy base of the filling, while whites form the edible shell.
- Melted butter
- Adds fat that makes the yolk paste smooth and rich in texture.
- Mustard
- Adds sharpness that balances the richness of the yolks and butter.
- Vinegar
- Adds acidity that brightens the flavor of the filling and the cresses.
The step that matters
Mash the yolks into a smooth paste. Yolks must be mashed fully with the butter before filling, because lumps leave an uneven texture. Adding the liquid ingredients gradually helps the paste blend evenly instead of separating.
Swap the mustard
How well each one fits the dish's main ingredients (egg, butter, pepper, vinegar, sugar):
- Capsicumfits better
- Mustardthe original
- Cucumberfits about as well
- Shallotfits less well
Fit is the average pairing score against egg, butter, pepper, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
