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 ↓
Peal Shrewsbury Cakes
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.
Make the dough
In a large bowl, mix the flour, butter, powdered sugar, and cinnamon until crumbly.
Add the eggs and work the mixture into a light paste.
Roll out the paste thinly, enough for each piece to be the size of a breakfast cup.
Cut into desired shapes and place on buttered baking sheets.
Bake
Preheat the oven to 400°F (200°C).
Bake the cakes quickly, pricking them with a fork as they rise to prevent burning.
Remove from the oven when just hard, being careful as they are very brittle.

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 cakes together as they bake.
- Unsalted butter
- Adds richness and tenderness, giving the cakes their crumbly texture.
- Powdered sugar
- Sweetens the dough and helps it brown evenly while it bakes.
- Eggs
- Bind the dough into a paste and add richness and structure.
The step that matters
Removing the cakes when just hard. Shrewsbury cakes are very brittle and continue to firm as they cool. Taking them out too late can over-brown and dry them, while taking them out too early leaves them soft and likely to break.
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.
