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 hard and then place them in cold water for 30 minutes.
Remove the shells and cut the eggs in half, taking out the yolks without breaking the whites.
Make the filling
Rub the yolks smooth.
Mix in the melted butter or olive oil, vinegar, salt, pepper, and mustard.
Stuff the egg whites with the yolk mixture.
Assemble and serve
Press the halves together.
Secure with a toothpick.
Serve on a bed of lettuce leaves.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Provide the whites that hold the filling and the yolks that are mashed into it.
- Melted butter or olive oil
- Adds fat and richness, making the yolk filling smooth and creamy.
- Vinegar
- Adds acidity that brightens the rich yolk filling.
- Mustard
- Adds sharp flavor that balances the richness of the yolks.
The step that matters
Taking out the yolks without breaking the whites. The whites form the cups that hold the filling, so a torn white leaks filling and looks untidy. Cutting the eggs cleanly and lifting out the yolks gently keeps each half intact.
Swap the lettuce
How well each one fits the dish's main ingredients (egg, butter, vinegar, pepper, mustard):

Fit is the average pairing score against egg, butter, vinegar, pepper, mustard. Candidates are from the same food group and used in at least 100 recipes.
