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 together the sugar and butter until smooth.
Add the beaten egg yolks, lemon rind, and lemon juice. Mix well.
Gradually add the flour.
Fold in the stiffly beaten egg whites.
Add the fruit and flavourings
Prepare the almonds, raisins, and citron by dredging them with 2 tablespoons of extra flour.
Fold the dredged fruits and nuts into the batter.
Add the nectarine extract, rose water, and brandy. Mix until combined.
Bake
Pour the batter into a greased cake pan.
Bake at 350°F (175°C) until golden and 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
- Creams with the sugar to give the cake its tender, rich crumb.
- Sugar
- Sweetens the cake and helps hold air when creamed with the butter.
- Egg yolks
- Add richness and emulsify the batter, helping it bind and set.
- Egg whites
- Whipped and folded in to lighten the batter and help it rise.
- Flour
- Builds the structure that sets as the cake bakes.
- Almonds
- Add body, richness and a moist, nutty texture to the crumb.
The step that matters
Folding in the egg whites. Whisked whites hold the air that lifts the batter. Folding gently with a spatula keeps that air in; stirring vigorously deflates the foam and leaves a dense cake.

Fit is the average pairing score against sugar, butter, egg, flour, almond, raisin, 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.
