Why it works: Flour and cinnamon are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 17,341 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.
Make the dough
Cream the butter and sugar together.
Add the flour and eggs, mixing until combined.
Freeze the dough overnight if possible.
Shape and bake
Roll out the dough very thin.
Brush with egg white.
Sprinkle with a mixture of granulated sugar and cinnamon.
Add nuts on top.
Bake in a 400°F (200°C) oven until golden.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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 give the dough richness and a tender, crumbly texture.
- Eggs
- Bind the flour and butter into a dough and add richness to the cookie.
- Flour
- Provides the structure that holds the dough together as it bakes.
- Sugar
- Sweetens the dough and helps it brown during baking.
- Egg white
- Brushed on top, it helps the sugar and cinnamon stick and gives a glossy, crisp finish.
The step that matters
Roll out the dough very thin. Thin dough bakes quickly into a crisp cookie. Thicker dough stays soft and doughy in the center and may not brown evenly before the edges overbake.
Swap the nuts
How well each one fits the dish's main ingredients (butter, sugar, flour, egg, cinnamon):
- Almondfits better
- Chestnutfits better
- Pistachiofits better
- Nutsthe original
Fit is the average pairing score against butter, sugar, flour, egg, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
“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.
