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 ↓
Duchesse 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.
Make the batter
Cream the butter and sugar together until light.
Add the eggs two at a time, beating for 10 minutes after each addition.
Sift together the flour and baking powder, then add to the butter mixture along with the cinnamon extract.
Mix until you have a medium thick batter.
Bake and finish
Pour the batter into small shallow square pans lined with thin white paper.
Bake in a steady oven at 350°F (175°C) for 30 minutes.
Once baked, remove from the oven and ice the cakes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give the cake a tender, rich crumb.
- Sugar
- Creamed with butter to help build a light texture and adds sweetness.
- Eggs
- Add structure and richness, and help the batter bind and rise.
- Baking powder
- Releases gas in the batter to help the cakes rise.
- Flour
- Provides the structure that sets as the cakes bake.
The step that matters
Beating the eggs in. Adding eggs two at a time and beating well after each addition keeps the emulsion stable and the batter smooth. Adding them too fast can cause curdling, which weakens the air held in the batter and affects the final crumb.
Swap the cinnamon
How well each one fits the dish's main ingredients (butter, sugar, egg, flour):
- Cinnamonthe original
- Nutmegfits about as well
- Jalapenofits less well
- Capersfits less well
Fit is the average pairing score against butter, sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
