Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Deviled Eggs
Ingredients
Directions
Prepare the filling
Remove the yolks from the hard-boiled eggs and place them in a bowl.
Mix the yolks with the mustard, olive oil, and seasonings using the back of a silver spoon.
Make the white sauce
In a chafing dish, combine the milk, butter mixed with cornstarch, finely chopped egg whites, and a little salt.
Stir constantly until the mixture is boiling hot.
Assemble and serve
Spread the yolk mixture thickly on slices of buttered toast.
Sprinkle the grated cheese over the toast.
Pour the hot white sauce on top and serve.

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 body of the filling; chopped whites add texture to the sauce.
- Butter
- Adds richness and fat, and with cornstarch helps thicken the white sauce.
- Milk
- Forms the liquid base of the white sauce, which thickens as it heats.
- Cornstarch
- Thickens the milk-based sauce when heated, giving it body.
- Dry mustard
- Adds sharp, pungent flavor that balances the richness of the yolks.
The step that matters
Stir constantly until the mixture is boiling hot. Cornstarch thickens only when heated to a boil and needs constant stirring; otherwise it can clump or stay thin, and milk can scorch on the bottom of the pan.
Swap the mustard
