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, mixing well.
Gradually incorporate the flour and then fold in the stiffly beaten egg whites.
Add the fruit and nuts
Prepare the almonds, raisins, and citron by dredging them with 2 tablespoons of extra flour.
Add the dredged fruits and nuts to the batter along with the nectarine extract, rose water, and brandy.
Bake
Pour the mixture into a prepared baking pan and bake at 350°F (175°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks enrich the batter, and whipped whites add lift and a light structure.
- Butter
- Creamed with sugar, it traps air and gives the cake a tender, rich crumb.
- Sugar
- Creamed with butter, it helps build a smooth base and adds sweetness and browning.
- Flour
- Provides the structure that sets the cake as it bakes.
- Almonds
- Add body, a nutty flavour, and a moist, chewy texture to the crumb.
- Raisins
- Add moisture and concentrated sweetness throughout the cake.
The step that matters
Fold in the stiffly beaten egg whites. Whites hold air only when whipped stiff and folded in gently; overmixing knocks out the air, leaving a denser cake that rises less in the oven.

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.
