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 ↓
Chocolate Fruit 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 together the soft sugar, butter, and brown sugar.
Add the sweet cream and melted chocolate, mixing well.
In a separate bowl, combine the flour and baking powder.
Beat the eggs and gradually add them to the sugar mixture.
Stir in the flour mixture, followed by the raisins, currants, citron, and spices.
Flour the fruit to prevent sinking.
Bake and finish
Pour the batter into a loaf pan and bake until a toothpick comes out clean.
Once cooled, cover with chocolate icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Raisins
- Add chewy sweetness and moisture throughout the cake.
- Currants
- Add chewy sweetness and moisture throughout the cake.
The step that matters
Flour the fruit to prevent sinking.. Heavy fruit sinks through batter during baking. Tossing it in flour helps it cling to the batter and stay suspended, so the fruit spreads evenly through the cake.
Swap the raisin
How well each one fits the dish's main ingredients (sugar, butter, cream, chocolate, flour, egg, nutmeg):
- Vanillafits better
- Raisinthe original
- Coconutfits less well
- Figfits less well
Fit is the average pairing score against sugar, butter, cream, chocolate, flour, egg, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
