Why it works: Raisin and flour 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 ↓
A Plum Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Whisk the eggs over a gentle heat until warm, then continue whisking until thick enough to hold a drop from the whisk.
Gradually mix in the sugar until thick and white.
Combine the raisins, currants, almonds, orange peel, citron, flour, and creamed butter.
Add the cinnamon and ginger, mixing well.
Bake and serve
Butter a cake hoop and pour the batter into it.
Smooth the top with a knife and glaze with sifted sugar.
Bake in a moderate oven at 350°F (175°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whisked until thick, they trap air and give the cake its light structure.
- Sugar
- Whisked with the eggs to add sweetness and help build a thick, pale foam.
- Flour
- Provides the main structure that sets as the cake bakes.
- Sweet butter
- Creamed into the batter to add richness, tenderness and moisture.
- Raisins
- Add moisture and concentrated sweetness throughout the cake.
- Almonds
- Add richness and a nutty flavor, along with some texture.
The step that matters
Whisking the eggs and sugar to a thick foam. The eggs must be whisked until thick enough to hold a drop, since this trapped air is what lifts the batter. Under-whisking leaves a dense cake.
Swap the currant
How well each one fits the dish's main ingredients (egg, sugar, raisin, almond, orange, flour, butter):
- Vanillafits better

Fit is the average pairing score against egg, sugar, raisin, almond, orange, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
