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 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Cream the butter and flour together.
Beat the egg yolks and sugar together.
Add the beaten egg whites to the yolk mixture.
Mix the yolk and white mixture with the creamed butter and flour.
Dredge the fruit with flour and gradually add it to the batter.
Stir in the whisky or brandy.
Bake
Bake in a loaf pan at 300°F (150°C) for four hours.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites trap air for lightness while yolks add richness and help bind the batter.
- Butter
- Creamed with flour, it adds richness and tenderness to the crumb.
- Light brown sugar
- Sweetens the cake and adds moisture and a caramel note.
- Flour
- Provides structure as the batter sets in the oven.
- Raisins
- Add chewy sweetness and moisture throughout the cake.
- Whisky or brandy
- Adds aroma and flavor and helps keep the cake moist.
The step that matters
Adding the beaten egg whites. Beaten whites hold air that gives the cake lift. Folding them in gently, rather than stirring hard, keeps that air from collapsing and keeps the batter light.
Swap the nutmeg
How well each one fits the dish's main ingredients (butter, sugar, flour, raisin, egg, almond, whisky):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Capersfits less well
Fit is the average pairing score against butter, sugar, flour, raisin, egg, almond, whisky. Candidates are from the same food group and used in at least 100 recipes.
