Why it works: Flour and raisin match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,075 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Imperial 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the flour gradually, mixing until just combined.
Fold in the raisins, citron, and blanched almonds.
Add the grated nutmeg and wine, mixing until evenly distributed.
Bake
Pour the batter into a greased cake pan and bake for about 1 hour or until a toothpick comes out clean.

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, giving the cake a tender, rich crumb.
- Eggs
- Add structure and richness as they set during baking, binding the batter together.
- Flour
- Forms the main structure of the cake as its proteins set in the oven.
- Sugar
- Sweetens the cake and helps create a light, fluffy texture when creamed with butter.
- Blanched almonds
- Add texture and a nutty flavour to the finished cake.
The step that matters
Adding the eggs one at a time. Eggs added too quickly can curdle the creamed butter and sugar, breaking the emulsion and reducing the cake's even, fine crumb. Mixing well after each egg keeps the batter smooth and able to hold air.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, sugar, flour, egg, raisin, almond, wine):
- Cinnamonfits better
- Nutmegthe original
- Capersfits less well
- Jalapenofits less well
Fit is the average pairing score against butter, sugar, flour, egg, raisin, almond, wine. Candidates are from the same food group and used in at least 100 recipes.
