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 ↓

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.
Prepare
Preheat your oven to 400°F (200°C).
Make the dough
In a bowl, cream the butter and sugar together.
Add the egg yolks and mix well.
In another bowl, beat the egg whites with 1 teaspoon of sugar until stiff peaks form.
Gently fold the egg whites into the butter mixture.
Stir in the flour to form a soft dough.
Shape and bake
Roll out the dough thinly and cut into desired shapes.
Place on a baking sheet and bake for about 10 minutes or until lightly golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the structure of the dough once mixed in.
- Butter
- Adds richness and tenderness, and carries flavor through the dough.
- White granulated sugar
- Creams with the butter for a tender texture and adds sweetness and browning.
- Eggs
- Yolks add richness and binding; whipped whites add lift and a lighter texture.
The step that matters
Gently fold the egg whites into the butter mixture. Whipped egg whites hold air bubbles that give lightness. Stirring them vigorously deflates the foam, so the cookies turn out denser and less tender.
