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 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 300°F (150°C).
Make the batter
In a large bowl, cream together the sugar and butter until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Gradually stir in the flour until fully combined.
Fold in the raisins, citron, currants, figs, molasses, brandy, cloves, cinnamon, nutmeg, and mace.
Bake
Pour the batter into a prepared cake pan.
Bake slowly for 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
- Bind the batter and add structure as the cake sets in the oven.
- Butter
- Adds richness and tenderness, and creaming it with sugar traps air for a lighter crumb.
- Flour
- Forms the main structure that holds the fruit and batter together as it bakes.
- Sugar
- Adds sweetness and, creamed with butter, helps give the batter its light texture.
- Raisins
- Add moisture, sweetness and chewy texture throughout the cake.
- Molasses
- Adds moisture, deep sweetness and a darker color to the cake.
The step that matters
Bake slowly until the center is set. Long, low heat lets the batter set evenly without scorching the outside, while the dense fruit needs time to cook through. Test the center with a toothpick before removing the cake.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, flour, egg, raisin, fig, molasses):
- Vanillafits better
- Datesfits better
- Applefits better
- Currantthe original
Fit is the average pairing score against sugar, butter, flour, egg, raisin, fig, molasses. Candidates are from the same food group and used in at least 100 recipes.
