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 choux dough
Boil the butter and water together.
Stir in the flour while boiling.
Let the mixture cool.
Add the 5 beaten eggs. Mix well.
Drop spoonfuls onto baking sheets.
Bake in a 400°F (200°C) oven until golden brown.
Make the filling
Heat the milk in a saucepan for the filling.
In a bowl, mix sugar, corn starch, and 2 eggs.
Gradually add the hot milk to the mixture. Stir constantly.
Return the mixture to the saucepan.
Cook until thickened.
Let the filling cool.
Assemble
Fill the cream puffs.

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 dough that holds the puffs' shape.
- Butter
- Adds fat and richness to the dough, helping it stay tender.
- Eggs
- Bind the dough and, as it bakes, help the puffs rise and set.
- Milk
- Gives the filling its liquid base and creamy body.
- Corn starch
- Thickens the filling as it heats, giving it a set, smooth texture.
- Sugar
- Sweetens the filling.
The step that matters
Adding the hot milk to the egg mixture. Pouring hot milk in too fast or without stirring can scramble the eggs. Adding it gradually while stirring constantly tempers the eggs so the filling thickens smoothly.
