Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. 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 dough
Boil the water in a pot.
Add the butter and stir until melted.
Remove from heat and stir in the flour until combined.
Let the mixture cool.
Add the eggs one at a time, mixing with your hands until fully incorporated.
Bake
Drop spoonfuls onto a buttered baking sheet, making them look rough.
Bake at 400°F (200°C) for 25 minutes; do not open the oven door for the first 15 minutes.

Flour and butter 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
- Flour
- Starch that gels with the hot water and butter to give the dough its structure.
- Eggs
- Add moisture and proteins that set during baking, helping the puffs rise and hold their shape.
- Butter
- Adds fat for tenderness and richness in the dough.
- Water
- Turns to steam in the oven, helping the puffs expand.
The step that matters
Do not open the oven door for the first 15 minutes. Steam from the water drives the puffs up, and the structure sets only as they bake. Opening the door early lets steam escape, so the puffs can collapse or stay flat.
“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.
