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 ↓
Knickerbocker 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
Preheat the oven to 350°F (175°C).
In a large bowl, beat the egg whites until stiff peaks form.
In another bowl, cream the butter and sugar until light and fluffy.
Gradually add the flour and baking powder, mixing well.
Fold in the beaten egg whites and lemon extract.
Bake and fill
Pour the batter into a large mold and bake until golden brown.
Once baked, let the cake cool, then split it into three layers.
Ice each layer with frosting and layer with grated coconut, chopped candy, figs, raisins, and almonds.
Decorate the outside with whole pieces of candy and additional raisins.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten to stiff peaks, they trap air that lightens the cake's structure.
- Butter
- Creamed with sugar, it adds tenderness and richness to the crumb.
- Sugar
- Creamed with butter, it sweetens the cake and helps give a light, fluffy texture.
- All-purpose flour
- Provides the main structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking, helping the cake rise and turn light.
The step that matters
Folding in the beaten egg whites. Folding gently keeps the air bubbles in the whipped whites. Stirring hard or too long knocks out that air, leaving a denser cake with less rise.
