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 slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat the oven to 300°F (150°C).
In a large bowl, rub the butter into the flour until well combined.
Beat the eggs until light and fluffy.
Gently mix the eggs and sugar into the flour mixture using your hands.
Let the mixture stand for 1-2 hours to stiffen.
Shape and bake
Roll out the dough and cut into desired shapes, dusting with sugar and flour.
Place on a baking sheet and bake in the preheated oven 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
- Provides the structure that holds the dough together as it bakes.
- Unsalted butter
- Adds fat that makes the dough tender and rich, and carries flavor.
- Eggs
- Bind the dough and add moisture and richness to the crumb.
- Granulated sugar
- Sweetens the dough and helps it brown lightly in the oven.
The step that matters
Let the mixture stand for 1-2 hours to stiffen. Resting lets the flour absorb the liquid from the eggs and fully hydrate, so the dough firms up and holds its shape when rolled and cut. Skipping the rest can leave a soft dough that spreads in the oven.
