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 paste
Boil the water and butter together.
Stir in the flour until a smooth paste forms.
Remove from heat and let cool slightly.
Add the 3 eggs and beat for 5 minutes.
Drop by tablespoons onto a greased pan.
Bake in a 400°F (200°C) oven for 20-25 minutes.
Make the filling
For the filling, cook the milk, sugar, 1 egg, and 2 tablespoons of flour thoroughly. Add flavoring to taste.
Fill and serve
When both the puffs and filling are cool, open the puffs at one side and fill.

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, tenderness and richness to the paste.
- Flour
- Starch sets with the egg and steam to give the puffs their structure.
- Eggs
- Provide structure and leavening as they expand with steam during baking.
- Milk
- Liquid base of the filling that thickens when cooked with flour and egg.
- Sugar
- Sweetens the filling and adds body to its texture.
The step that matters
Let the cooked paste cool slightly before adding the eggs. If the paste is still very hot, the eggs can scramble instead of blending smoothly. Beating them in gradually keeps the dough glossy and able to trap the steam that makes the puffs rise.
