Why it works: Lemon and cinnamon match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 7,950 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Imperial Cake
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
In a large bowl, cream the butter and sugar together until light and fluffy.
Make the batter
Add the eggs one at a time, mixing well after each addition.
Stir in the flour, baking soda mixture, currants, lemon rind, lemon juice, and cinnamon until just combined.
Bake
Drop spoonfuls of the batter onto well-buttered parchment paper lining a baking pan.
Bake quickly until golden brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the main structure that sets the batter as it bakes.
- Butter
- Creaming with sugar traps air and adds tenderness and richness.
- Sugar
- Sweetens the cake and helps create a light, fluffy texture when creamed.
- Eggs
- Add structure, binding, and richness as they set in the batter.
- Baking soda
- Reacts with the batter to help it rise and promote browning.
- Currants
- Add chewy pockets of fruit sweetness throughout the cake.
The step that matters
Bake quickly until golden brown. Dropped spoonfuls are thin and small, so they can dry out or over-brown if left too long. Watching for golden color and removing them promptly keeps them moist. Baking soda needs to be mixed in promptly after dissolving, since its leavening power fades once it sits.
Swap the currant
How well each one fits the dish's main ingredients (flour, butter, sugar, egg, lemon, cinnamon):

Fit is the average pairing score against flour, butter, sugar, egg, lemon, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
