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 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 dough
In a bowl, cream the sugar into the eggs after beating them separately.
Add the melted butter to the egg yolks, then fold in the egg whites.
Mix in the flour and baking powder until combined.
Shape and bake
Roll the dough thin and cut into desired shapes.
Bake in the preheated oven until lightly golden.

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, richness and binding, with the whites adding lightness to the dough.
- Flour
- Forms the gluten network that gives the dough its structure once rolled and baked.
- Butter
- Adds fat for tenderness and rich flavour in the finished cakes.
- Sugar
- Adds sweetness and helps the surface brown lightly in the oven.
- Baking powder
- Releases gas in the dough so the cakes rise and become lighter in texture.
The step that matters
Folding in the egg whites. Egg whites hold air that gives the dough lightness. Stirring them vigorously or overmixing deflates this foam, leaving dense cakes, so fold gently until just combined.
“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.
