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 ↓
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 the butter and sugar together until light and fluffy.
Add the flour, molasses, brandy, and eggs, mixing well.
Dissolve the baking soda in a little hot water and add to the mixture.
Fold in the citron, currants, and raisins, ensuring they are well dried and floured.
Top and bake
Reserve some of the dough without fruit to cover the top of the cake.
Spread the reserved dough over the fruit to prevent burning.
Pour the batter into a greased cake pan and bake for several hours until done.

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
- Butter
- Creamed with sugar to trap air and add richness and tenderness.
- Sugar
- Creamed with butter for a light texture and adds sweetness.
- Flour
- Provides the structure that holds the fruit and crumb together.
- Eggs
- Bind the batter and add structure and richness as they set.
- Baking soda
- Reacts with the acidic molasses to produce gas that helps the cake rise.
- Molasses
- Adds moisture, dark color, and a deep, slightly acidic flavor.
The step that matters
Baking the long cake with a fruit-free cover. The batter is baked for several hours, so the top can burn before the center sets. The plain dough layer shields the fruit, and the cake must be fully baked through to set the batter.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, flour, molasses, brandy, egg, raisin):
- Vanillafits better
- Figfits better
- Currantthe original
- Applefits about as well
Fit is the average pairing score against butter, sugar, flour, molasses, brandy, egg, raisin. Candidates are from the same food group and used in at least 100 recipes.
