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
Make the puffs
Boil water and butter together.
Stir in flour, then remove from heat.
Add eggs one at a time, mixing well after each addition.
Stir in baking soda.
Drop spoonfuls onto a greased baking pan to form round cakes.
Bake until golden brown.
Make the filling and assemble
For the filling, cook milk, beaten eggs, sugar, and corn starch until thickened.
Once cakes are cool, cut them open and fill with the prepared mixture.

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
- Eggs
- Bind the dough and, as they set, give the puffs their structure and hollow centre.
- Flour
- Provides the starch and gluten that set the choux dough around the steam.
- Butter
- Melts into the boiling water to add fat and tenderness to the dough.
- Milk
- Forms the base of the custard filling, giving it body and richness.
- Corn starch
- Thickens the custard filling so it holds its shape when cut and filled.
- Sugar
- Sweetens the custard filling.
The step that matters
Bake until golden brown. Puffs need enough baking for the starch and egg structure to set and dry out; underbaked shells collapse or turn soggy once cooled and filled.
“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.
