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 filling
Boil the eggs for 20 minutes.
Cut the eggs in half lengthwise and remove the yolks.
Mash the yolks finely and mix in salt, cayenne, mustard, butter or oil, thick cream, and vinegar.

Assemble and serve

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites provide the shell for the filling, and cooked yolks become the creamy base.
- Butter or oil
- Adds fat, giving the yolk filling a smoother, richer texture.
- Thick cream
- Adds moisture and richness, loosening the mashed yolks into a spreadable paste.
- Mustard
- Adds sharpness that balances the richness of the yolks and fat.
- Vinegar
- Adds acidity that brightens the flavour of the rich yolk filling.
The step that matters
Beat the mixture until it forms a stiff paste. Mashing and beating break the yolks into fine particles and blend in the fat and cream, so the filling becomes smooth and holds its shape when spooned back into the whites.
