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 ↓
Scotch Bread
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).
In a large bowl, mix the flour, sugar, ammonia, butter, and cinnamon until well combined.
Add the eggs one at a time, mixing thoroughly after each addition.
Shape and bake
Roll the dough to a thickness of 1 inch or less and scallop the edges.
Bake until golden brown.
Serve
Stack three or four cakes on top of one another and cut into slices.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the main structure of the dough as its proteins and starches set on baking.
- Eggs
- Bind the mixture and add structure and richness as they set in the oven.
- Sugar
- Adds sweetness and helps the crumb stay tender and browned at the surface.
- Butter
- Adds fat that tenderizes the crumb and carries flavor through the dough.
- Ammonia
- Releases gas as it heats, helping the dough rise and lighten during baking.
- Cinnamon
- Contributes the warm, aromatic flavor that defines the bread.
The step that matters
Roll the dough to a thickness of 1 inch or less. Thickness controls how evenly heat reaches the center. Dough rolled thicker than about 1 inch may stay doughy inside while the outside browns too quickly, so keeping it thin helps the whole piece bake through evenly.
Swap the cinnamon
How well each one fits the dish's main ingredients (flour, egg, sugar, butter):
- Cinnamonthe original
- Nutmegfits about as well
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against flour, egg, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
