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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the choux paste
Combine the melted butter and hot water in a double boiler and bring to a boil.
Stir in the flour while boiling, then remove from heat and let cool.
Stir in the eggs one at a time until well combined.
Drop spoonfuls of the mixture into buttered tins.
Bake and make the filling
Bake in a hot oven at 400°F (200°C) until golden.
Cook the milk, egg, and sugar in a saucepan.
Thicken the mixture with cornstarch or flour as desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and set the puffs as they bake, and bind the paste.
- All-purpose flour
- Gives the paste body so it holds its shape around the steam.
- Butter
- Adds richness and tenderness to the paste.
- Milk
- Forms the liquid base of the filling and adds creaminess.
- Sugar
- Sweetens the filling.
- Cornstarch
- Thickens the filling as it cooks.
The step that matters
Let the paste cool before adding the eggs. If the paste is still very hot when the eggs go in, they can scramble or thin the mixture, so it may not hold its shape or puff properly in the oven.
