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 ↓
Dutch Puffs
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Make the batter
In a large bowl, beat together the sugar and butter until creamy.
Add the flour and the beaten egg yolks, mixing continuously to keep the batter light.
Stir in the lemon juice and grated rind, followed by the baking powder.
In a separate bowl, beat the egg whites until stiff peaks form, then gently fold them into the batter.
Bake and serve
Pour the mixture into round molds and bake until golden.
Serve warm with a hot sauce.

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, creaming with sugar traps air for a tender crumb.
- Egg whites
- Whipped to stiff peaks, they add lift and an airy structure to the batter.
- Egg yolks
- Add richness and help bind the batter while adding moisture and colour.
- Flour
- Provides the structure that holds the puffs together as they set in the oven.
- Baking powder
- Releases gas in the batter, helping the puffs rise and become light.
- Granulated sugar
- Sweetens the batter and, creamed with butter, helps create a light texture.
The step that matters
Folding in the egg whites. Stiff whites hold the air that makes the puffs rise. Folding gently keeps that air in, while vigorous stirring deflates the batter and produces dense, flat puffs.
