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 ↓
Ckeam Puffs
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Melt the butter in hot water.
While boiling, beat in the flour.
Remove from the stove and let cool.
Stir in the eggs one at a time without beating.
Bake the puffs
Drop spoonfuls onto baking sheets.
Bake for about 25 minutes at 350°F (175°C).
Make and fill the cream
For the cream, boil the milk with 1 egg, sugar, and flour.
Flavor the cream with lemon.
When the puffs are done, open the side with a sharp knife and fill with the cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts into the hot water to form the liquid base, adding richness and tenderness to the dough.
- All-purpose flour
- Starch that thickens with the boiling water and sets the dough's structure as it bakes.
- Eggs
- Bind the dough and, as they set in the oven, give the puffs their structure and lift.
- Milk
- Forms the base of the cream, which thickens as it cooks with the flour and egg.
- Sugar
- Sweetens the cream filling.
The step that matters
Stir in the eggs one at a time without beating. Eggs added to a paste that is still too hot can scramble, and beating knocks out the air the dough needs. Adding them gently one at a time gives a smooth, stretchy dough that puffs up around a hollow centre in the oven.
Swap the lemon

Fit is the average pairing score against butter, flour, egg, milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
