Why it works: Cinnamon and flour 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 ↓
Shrewsbury Cakes
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Beat the butter in a pan until smooth and creamy.
Add the powdered sugar, cinnamon, mace, and eggs. Mix well with your hands.
Gradually incorporate the flour until the dough is well combined.
Shape and bake
Roll out the dough on a flat surface until thin.
Cut into desired shapes and sizes.
Bake in a slow oven at 300°F (150°C) until they just change color.

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
- Creates a rich, tender crumb and carries the flavor of the spices.
- Powdered sugar
- Sweetens the dough and dissolves easily into the creamed butter for a fine texture.
- Eggs
- Bind the dough and add richness and structure as the cookies set.
- All-purpose flour
- Provides the structure that holds the rolled and cut shapes together.
The step that matters
Baking until they just change color. Shrewsbury cakes are meant to stay pale and tender. Baking past the point where the edges just change color dries them out and drives browning, which makes them hard and crisp.
Swap the mace
How well each one fits the dish's main ingredients (butter, sugar, cinnamon, egg, flour):
- Nutmegfits better
- Cardamomfits better
- Allspicefits better
- Macethe original
Fit is the average pairing score against butter, sugar, cinnamon, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
