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 says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the puff dough
In a saucepan, boil the butter and water together.
Stir in the flour while boiling until combined.
Let the mixture cool.
Add the 5 beaten eggs to the mixture and mix well.
Drop spoonfuls of the mixture onto baking tins.
Bake the puffs
Bake in a preheated oven at 400°F (200°C) until golden.
Make the filling
Boil the milk for the filling.
Stir in the sugar, corn starch, and 2 beaten eggs.
Cook until thickened.
Flavor with lemon or vanilla.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the choux paste that holds the puffs' shape.
- Eggs
- Add structure and richness to the paste and help the puffs rise and set.
- Butter
- Adds fat and richness, and tenderness to the choux paste.
- Milk
- Provides the liquid base of the filling.
- Corn starch
- Thickens the filling as it heats.
- Sugar
- Sweetens the filling.
The step that matters
Bake until golden. Steam from the water and butter must expand the paste while the structure sets. Underbaked puffs collapse as they cool, so bake until they are fully golden and firm.
