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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Preheat the oven to 350°F (175°C).
Rub the butter into the flour until well combined.
Add the sugar and mix well.
Wet the mixture with the egg whites and yolks.
Roll the dough very thin and cut into diamond shapes.
Finish and bake
Glaze the tops with the egg white.
Sprinkle with chopped nuts and ground cinnamon.
Bake until lightly 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
- Rubbed into the flour to coat it and create a tender, crumbly texture.
- All-purpose flour
- Forms the structure of the dough once bound with liquid.
- Sugar
- Adds sweetness and helps the cookies brown during baking.
- Egg whites
- Bind the dough and add structure, and glaze the tops for a sheen.
- Egg yolks
- Add richness and fat, contributing to a tender dough.
The step that matters
Roll the dough very thin. Thin dough bakes through and turns crisp; thick pieces stay soft in the center and may not brown evenly, so the thickness should be uniform across all diamonds.
Swap the nuts
How well each one fits the dish's main ingredients (butter, flour, sugar, egg, cinnamon):
- Almondfits better
- Chestnutfits better
- Pistachiofits better
- Nutsthe original
Fit is the average pairing score against butter, flour, sugar, 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.
