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 ↓
Plain Fruit Cake
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Preheat the oven to 300°F (150°C).
Cream the butter and brown sugar together until light and fluffy.
Add the egg yolks and mix well.
Stir in the milk, raisins, currants, mixed peel, cinnamon, lemon extract, and grated nutmeg.
Sift the flour and baking powder together, then gradually add to the mixture.
In a separate bowl, beat the egg whites until stiff peaks form, then fold them into the batter.
Bake
Pour the batter into a greased cake pan.
Bake for 3 to 4 hours, or until a toothpick inserted in the center comes out clean.

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, while whipped whites lighten it and add structure as the cake sets.
- All-purpose flour
- Provides the wheat proteins and starch that form the cake's structure as it bakes.
- Unsalted butter
- Creamed with the sugar to trap air, adding tenderness and richness to the crumb.
- Brown sugar
- Sweetens the cake, adds moisture, and creamed with butter helps create a tender texture.
- Baking powder
- Releases gas during baking, helping the cake rise and become light.
- Raisins
- Add chewy sweetness and moisture to the cake.
The step that matters
Folding in the egg whites. Whipped whites hold the air that lightens the batter. Folding gently, rather than stirring, keeps that air from collapsing, so the cake rises well and stays light.
Swap the currant
How well each one fits the dish's main ingredients (flour, butter, sugar, egg, milk, raisin, cinnamon):
- Vanillafits better
- Figfits better
- Applefits better
- Currantthe original
Fit is the average pairing score against flour, butter, sugar, egg, milk, raisin, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
