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 dough
Boil 1 cup water and ½ cup butter until the butter is dissolved.
Add 1 cup flour and stir until smooth. Set aside to cool.
Add 3 eggs and beat until free from lumps.
Bake and fill
Bake in muffin tins at 400°F (200°C) for about 30 minutes.
When cool, slit along one side and fill with sweetened whipped cream or custard.
Make the custard
For custard, beat 2 eggs with ½ cup sugar.
Dissolve 2 tablespoons cornstarch in ½ cup milk.
Heat 1½ cups milk, add cornstarch, and boil until thickened.
Add the egg and sugar mixture, and boil for a few more minutes.
Remove from heat and add flavoring.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts into the boiling water to add fat and richness to the dough.
- Flour
- Starch that gelatinises with the eggs to give the puffs their structure.
- Eggs
- Set during baking and provide structure, rise and richness in the puffs.
- Cornstarch
- Thickens the milk into a custard that holds its shape when filled.
- Sugar
- Adds sweetness and helps soften the egg custard as it sets.
- Milk
- Provides liquid and body for the custard filling.
The step that matters
Add the egg and sugar mixture to the thickened milk. Eggs can scramble if added to very hot liquid too quickly. Stirring constantly while adding them, then boiling briefly, lets the custard thicken smoothly.
