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. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 400°F (200°C).
Make the dough
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the beaten eggs, lemon juice, and lemon rind, mixing well.
Gradually add the flour, stirring until combined.
Roll the dough very thin on a floured surface.
Shape and bake
Cut into desired shapes and sprinkle with coarse sugar.
Place on a baking sheet and bake for about 10-12 minutes or 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
- Butter
- Creams with sugar to trap air and give a tender, rich texture.
- Sugar
- Sweetens the dough and, creamed with butter, helps it turn light and fluffy.
- Flour
- Provides the structure that holds the dough together after baking.
- Eggs
- Bind the dough and add richness and structure.
- Lemon juice
- Adds acidity and bright lemon flavor.
The step that matters
Rolling the dough very thin. Thin dough bakes quickly and evenly. If it is thick, the centre stays soft while the edges over-brown, so the cookies lose their crisp texture.
Swap the lemon
How well each one fits the dish's main ingredients (butter, sugar, flour, egg):

Fit is the average pairing score against butter, sugar, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
