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
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the flour, walnuts, raisins, citron, mace, and brandy until well combined.
Pour the batter into a greased cake pan.
Bake
Bake for about 1 hour or until a toothpick inserted in the center comes out clean.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Eggs
- Bind the batter and add structure and richness as the cake sets.
- Butter
- Adds fat and richness, and creaming it with sugar traps air for a tender crumb.
- Sugar
- Sweetens the cake and helps create a light, fluffy texture when creamed with butter.
- Flour
- Provides the structure that holds the cake and fruit together as it bakes.
- English walnuts
- Add texture and nutty flavor to the crumb.
- Raisins
- Add moisture and concentrated sweetness throughout the cake.
The step that matters
Creaming the butter and sugar. Beating butter and sugar until light and fluffy traps air bubbles that expand in the oven and lighten the crumb. Under-creaming leaves a dense cake, while adding eggs too quickly can cause the batter to curdle and lose air.
Swap the mace
How well each one fits the dish's main ingredients (egg, butter, sugar, flour, walnut, raisin, brandy):
- Cinnamonfits better
- Nutmegfits better
- Capersfits better
- Macethe original
Fit is the average pairing score against egg, butter, sugar, flour, walnut, raisin, brandy. Candidates are from the same food group and used in at least 100 recipes.
