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 ↓
Cinnamon Cake
Ingredients
Directions
The book says “a steady oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, mix sugar, butter, flour, and cinnamon.
Beat the egg whites to a froth and add to the mixture.
Stir in the rum and combine well.
Bake
Pour the batter into a greased cake pan and bake until golden.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Adds fat that keeps the cake tender and moist while it bakes.
- Flour
- Provides the structure that holds the cake together as it sets.
- Egg whites
- Whipped to a froth, they add lift and help set the cake's structure.
- Sugar
- Sweetens the cake and helps it brown as it bakes.
The step that matters
Beat the egg whites to a froth. Whipped egg whites trap air that gives the batter lift. If they are under-beaten, the cake may be dense; if over-beaten, they can collapse and lose their airy structure when folded in.
Swap the cinnamon
How well each one fits the dish's main ingredients (sugar, butter, flour, egg, rum):
- Cinnamonthe original
- Nutmegfits about as well
- Jalapenofits less well
- Gingerfits less well
Fit is the average pairing score against sugar, butter, flour, egg, rum. Candidates are from the same food group and used in at least 100 recipes.
