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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Cream the butter with the sugar.
Add the beaten eggs gradually, mixing for a few minutes between each addition.
Sift the flour and baking powder together six times.
Add the flour mixture and cinnamon to the butter mixture and mix into a medium thick batter.
Bake and finish
Bake in small, shallow, square pans lined with thin white paper at 350°F (175°C) for about 30 minutes.
Let cool and then ice the cakes.

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
- Creams with sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Add structure and richness, helping the batter set as it bakes.
- Flour
- Forms the structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- White sugar
- Sweetens the cake and helps hold air in the creamed butter.
The step that matters
Adding the beaten eggs gradually. Adding eggs slowly, with mixing between additions, lets the emulsion form properly. Adding them all at once can split the batter and affect the final texture.
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.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
