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 Puff
Ingredients
Directions
The book says “a fairly hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the pastry
Boil ½ cup hot water and ½ cup butter in a saucepan.
Stir in 1 cup all-purpose flour while boiling.
Let the mixture cool, then stir in 4 eggs one at a time without beating.
Shape and bake
Drop spoonfuls of the mixture onto a baking sheet.
Bake in a fairly hot oven at 400°F (200°C).
Make the cream
For the cream, combine 1 pint milk, 3 tablespoons flour, 1 egg, and ½ cup sugar in a saucepan.
Cook until thickened, then let cool before using.

Butter and flour 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
- All-purpose flour
- Starch and gluten give the paste the structure to hold its shape and puff.
- Eggs
- Set the paste as it bakes and their steam helps the puffs rise hollow.
- Butter
- Adds fat that enriches the paste and gives a tender, rich texture.
- Milk
- Forms the liquid base of the cream, which thickens as its starch gelatinizes.
- Sugar
- Sweetens the cream and adds body to its flavor.
The step that matters
Adding the eggs to the paste. If the paste is still hot, the eggs can scramble. Stirring them in gently, one at a time, keeps the dough smooth and stiff enough to hold its shape and rise.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
