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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Cream the butter and sugar together.
Stir in the well-beaten egg.
Add the orange juice and sifted flour with baking powder.
Mix in the grated orange rind.
Shape and bake
Roll out the dough very thin and cut with a cookie cutter.
Bake in a moderate oven at 350°F (175°C) until 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
- Creamed with sugar to trap air and give the cookies a tender, rich texture.
- Sugar
- Sweetens the dough and, creamed with butter, helps lighten its texture.
- Egg
- Binds the dough and adds structure and richness.
- Flour
- Provides the main structure that holds the cookies together as they bake.
- Baking powder
- Releases gas during baking so the cookies rise and turn light.
- Orange juice
- Adds moisture and bright citrus acidity to the dough.
The step that matters
Roll out the dough very thin. Thin dough bakes quickly and evenly, so it turns crisp and golden. Thick dough stays soft in the middle and can brown unevenly before it is fully baked.

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.
