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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Mix the flour, butter, powdered sugar, and cinnamon in a bowl, breaking the butter into small pieces with your hands.
Work the mixture into a light paste.
Shape
Roll out the paste thinly until an ounce weighs as much as the top of a small basin.
Cut into shapes and place on buttered paper.
Bake and serve
Bake in a quick oven at 400°F (200°C) for about 2 hours, pricking the cakes as they rise.
Carefully remove from the oven to avoid breaking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the paste that holds the cakes together as they bake.
- Butter
- Adds fat that makes the cakes tender and crumbly rather than tough.
- Powdered sugar
- Sweetens the cakes and dissolves fine enough to give an even texture.
- Cinnamon
- Adds warm aroma and flavour to the cakes.
The step that matters
Roll out the paste thinly. Thickness controls how the cakes bake. Thin, even pieces dry and brown through evenly, while uneven thickness leaves some cakes soft and others overbaked.
Swap the cinnamon
How well each one fits the dish's main ingredients (flour, butter, sugar, egg):
- Cinnamonthe original
- Nutmegfits about as well
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against flour, butter, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
