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 ↓
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.
Prepare the batter
Preheat the oven to 300°F (150°C).
In a large bowl, mix the raisins and currants with a little flour to coat them.
In another bowl, cream the butter and sugar together until light and fluffy.
Add the egg yolks one at a time, mixing well after each addition.
Stir in the brandy, wine, cloves, allspice, cinnamon, nutmeg, and almond slices.
Fold in the flour and the coated fruit mixture.
In a separate bowl, beat the egg whites until stiff peaks form, then gently fold them into the batter.
Bake
Pour the batter into a greased cake pan and smooth the top.
Bake for 3 hours, or until a toothpick inserted in the center comes out clean.

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
- Eggs
- Yolks enrich and bind the batter, while whipped whites lighten its structure as it bakes.
- Butter
- Creamed with sugar, it traps air and gives the cake a tender, rich crumb.
- Flour
- Its proteins set during baking, giving the cake the structure that holds the fruit.
- Sugar
- Creamed with butter it aids aeration, and it adds sweetness and helps browning.
- Raisins
- Dried fruit that stays moist and chewy, adding sweetness and body to the crumb.
- Molasses
- Adds moisture, dark color, and a deep, slightly bitter sweetness.
The step that matters
Folding in the beaten egg whites. Whites hold air only while stiff; overmixing or stirring them in deflates the foam, so the cake bakes up dense instead of light. Fold gently and keep the batter airy.
Swap the currant
How well each one fits the dish's main ingredients (raisin, butter, sugar, flour, egg, brandy, wine):
- Vanillafits better
- Figfits better
- Applefits about as well
- Currantthe original
Fit is the average pairing score against raisin, butter, sugar, flour, egg, brandy, wine. Candidates are from the same food group and used in at least 100 recipes.
