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 ↓
Cream Puffs
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the choux paste
Mix cold water and flour until smooth.
Combine the flour mixture with butter and stir over medium heat until it forms a thick paste.
Remove from heat and let cool slightly.
Add eggs one at a time, beating well after each addition.
Shape and bake
Drop spoonfuls of the mixture onto a buttered baking sheet, spacing them apart.
Preheat the oven to 400°F (200°C).
Bake until puffed and golden.
Make the custard
Combine milk, beaten eggs, flour or cornstarch, and sugar in a heatproof bowl.
Cook the mixture in a double boiler, stirring until smooth and thickened.
Fill and serve
Make a small slit in the side of each puff.
Fill each puff with 1 tablespoon of custard.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the starch and structure that hold the choux paste and custard together.
- Eggs
- Set the paste's structure as it bakes and help it puff and stay airy.
- Butter
- Adds fat to the paste, giving a tender interior and richer flavor.
- Milk
- Forms the liquid base of the custard, adding richness and body.
- Sugar
- Sweetens the custard and balances its flavor.
The step that matters
Add eggs one at a time, beating well after each addition. Each egg must fully blend into the warm paste before the next goes in. Adding them too fast can make the dough split or stay loose, so the puffs may not rise well or hold their shape.
Swap the lemon
How well each one fits the dish's main ingredients (flour, butter, egg, milk, sugar):

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