Why it works: Pepper and lettuce are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 4,037 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Deviled Eggs
Ingredients
Directions
Cook the eggs
Place the eggs in a kettle of boiling water.
Remove from heat and let stand for 40 to 45 minutes.
Plunge the eggs into cold water to prevent discoloration.
Shell the eggs carefully and cut them lengthwise.
Fill and serve
Remove the yolks and crumble them finely.
Add salt, pepper, and melted butter to the yolks.
If desired, mix in finely chopped cold boiled ham.
Fill the egg whites with the yolk mixture.
Serve cold on lettuce leaves.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide the yolk filling and the white shells that hold it.
- Melted butter
- Adds fat and richness, making the crumbled yolk mixture smooth and creamy.
The step that matters
Plunge the eggs into cold water. Cooling the eggs quickly stops residual heat from cooking them further, which prevents the green-gray ring that forms between yolk and white and keeps the yolks bright and easy to crumble.
Swap the lettuce
How well each one fits the dish's main ingredients (egg, pepper, butter, ham):
- Capsicumfits better
- Asparagusfits better
- Mustardfits better
- Lettucethe original
Fit is the average pairing score against egg, pepper, butter, ham. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
