Why it works: Mustard and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,356 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Deviled Eggs
Ingredients
Directions
Prepare the eggs
Boil the eggs for 20 minutes.
Shell the eggs and cut them in half.
Remove the yolks and mix with mustard, pepper, salt, and vinegar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the structure of the filling and the white shells that hold it.
- Mustard
- Adds sharp, pungent flavor that cuts the richness of the yolks.
- Vinegar
- Adds acidity that brightens the rich yolk filling.
- Melted butter
- Adds fat that makes the yolk mixture smooth and creamy.
The step that matters
Add melted butter to achieve a smooth paste. Yolks are crumbly on their own. Fat from melted butter coats the yolk particles and helps them blend into a smooth, creamy filling. Adding it slowly while mixing helps prevent a greasy or lumpy result.
Swap the lettuce
