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
Cream the butter and sugar together until light and fluffy.
Add the well-beaten eggs, flour, brandy, and fruit to the mixture.
Mix in the baking powder sifted with the flour.
Pour the batter into cake pans.
Bake
Bake for one hour.

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
- Butter
- Creaming with sugar traps air and adds richness and a tender crumb.
- Eggs
- Bind the batter and add structure as they set during baking.
- Flour
- Forms the cake's main structure once it sets in the oven.
- Baking powder
- Releases gas in the batter, helping the cake rise.
- Raisins
- Add moisture and chewy sweetness throughout the cake.
- Sugar
- Sweetens the cake and helps create a light, aerated batter when creamed.
The step that matters
Creaming the butter and sugar. Beating until light and fluffy incorporates air that gives the cake lift. Under-creamed butter leaves a dense texture, while the batter must be mixed gently after the flour goes in to avoid toughening it.
