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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the choux
Melt the butter in hot water in a saucepan.
While boiling, beat in the flour until combined.
Remove from heat and let cool.
Once cool, stir in the eggs one at a time without beating.
Bake and fill
Drop spoonfuls onto baking sheets and bake for about 25 minutes at 350°F (175°C).
For the cream, boil the milk, one egg, sugar, and flour together until thickened.
Flavor with lemon.
When baked, open the side of each puff and fill with the cream.

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
- Provide structure and leavening as steam expands the dough, setting the shells.
- All-purpose flour
- Gives the dough body so it holds its shape around the steam inside.
- Butter
- Adds fat and richness, and softens the dough for a tender shell.
- Milk
- Forms the base of the cream, giving it body and a soft, rich texture.
- Sugar
- Sweetens the cream filling and contributes to its thickened texture.
The step that matters
Stir in the eggs without beating. Eggs must be added gradually and mixed gently so the dough stays thick enough to hold its shape and puff in the oven rather than spreading or going thin.
Swap the lemon
How well each one fits the dish's main ingredients (butter, flour, egg, milk, sugar):

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.
