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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a large bowl, cream together the butter and sugar with a little rose water.
Beat the eggs separately and add them to the mixture.
Stir in the flour, raisins, almonds, citron, currants (if using), brandy, rose water, lemon juice, and lemon rind.
If desired, add mace and baking soda to improve flavor.
Bake
Pour the batter into three loaf pans.
Bake for about 1 hour or until a toothpick inserted in the center comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat that creates a tender, rich crumb when creamed with sugar.
- Sugar
- Sweetens the cake and helps trap air when creamed with butter.
- Flour
- Provides the structure that sets the batter as the cake bakes.
- Baking soda
- Reacts with acidic ingredients to help the cake rise.
- Almonds
- Contribute nutty flavor and a slightly firm, crunchy texture.
- Raisins
- Add chewy texture and concentrated sweetness throughout the cake.
The step that matters
Testing for doneness at the end of baking. Starch and egg proteins set as the batter bakes. Overbaking drives off too much moisture, leaving a dry, crumbly cake, so check the center with a toothpick.
Swap the currant
The recipe marks currant as optional. How well each one fits the dish's main ingredients (butter, sugar, flour, raisin, almond, brandy, rose):
- Vanillafits better
- Figfits better
- Apricotfits better
- Currantthe original
Fit is the average pairing score against butter, sugar, flour, raisin, almond, brandy, rose. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
