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.
Make the batter
Cream the butter and sugar together until light and fluffy.
Beat the egg yolks and mix them with the creamed butter and sugar.
Add the beaten egg whites and mix well.
Gradually fold in the flour.
Dredge the raisins and almonds with flour and add them to the mixture.
Stir in the grated nutmeg and citron.
Add the whisky or brandy and mix until combined.
Bake
Pour the batter into a loaf pan and bake at 350°F (175°C) for four hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and lift as the cake sets.
- Butter
- Adds richness and a tender crumb when creamed with sugar.
- Flour
- Provides the structure that holds the heavy fruit and nuts in place.
- Light brown sugar
- Adds sweetness, moisture and a caramel note to the crumb.
- Raisins
- Add chewy sweetness and moisture throughout the cake.
- Blanched almonds
- Add crunch and a nutty flavor that balances the sweetness.
The step that matters
Folding in the flour. Overmixing once flour is added develops gluten, which toughens the crumb. Fold gently and only until no dry flour streaks remain, so the cake stays tender despite its heavy load of fruit and nuts.
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.
