Why it works: Butter and flour 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 ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
In a saucepan, combine butter and water; bring to a boil.
Stir in flour quickly until a smooth dough forms.
Let the dough cool slightly, then beat in the egg white.
Bake
Drop batter from a teaspoon onto greased paper in a baking pan, making each piece the size of a pea.
Bake at 400°F (200°C) until light and crisp.

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
- Butter
- Adds fat and richness, giving the dough a tender, flavourful bite.
- Water
- Boils with the butter to create steam that helps the puffs rise and go hollow.
- Dry flour
- Gelatinizes with the hot liquid to form a structure that holds the puffs together.
- Egg white
- Adds moisture and protein that set in the oven, helping the puffs rise and crisp.
The step that matters
Stir in flour quickly until a smooth dough forms. Flour added to boiling liquid must be mixed fast so it gelatinizes evenly and doesn't form lumps. Smooth, well-cooked dough traps steam and bakes into hollow puffs.
“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.
