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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the dough
Preheat the oven to 350°F (175°C).
In a bowl, cream together the butter and light brown sugar.
Add the egg yolks and 1 egg white (beaten) to the mixture and mix well.
Stir in the flour and baking powder until combined.
Roll out the dough thinly on a floured surface.
Top and bake
Spread the reserved beaten egg white over the rolled dough.
Sprinkle ground cinnamon and granulated sugar on top.
Cut the dough into squares with a knife.
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
- Butter
- Adds richness and tenderness, helping the cookie stay short and crisp.
- Light brown sugar
- Adds sweetness and moisture, and helps the surface brown during baking.
- Eggs
- Bind the dough and add structure, while the beaten white gives the topping a glossy coat.
- Flour
- Provides the structure that holds the thin rolled dough together.
- Baking powder
- Releases gas in the oven, giving the cookie a light, tender lift.
The step that matters
Bake until lightly golden. Thin dough browns quickly and can go from golden to dry or burnt in minutes. Pulling it when lightly golden keeps it crisp but tender, since it keeps firming as it cools.
Swap the cinnamon
How well each one fits the dish's main ingredients (sugar, butter, egg, flour):
- Cinnamonthe original
- Nutmegfits about as well
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against sugar, butter, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
