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 brown sugar and butter.
Add the flour, raisins, currants, citron, cloves, mace, sour cream, baking soda, and dark jelly. Mix well.
Dredge the fruit with a little flour to prevent sinking.
Pour the batter into a greased cake pan.
Bake
Bake for 3 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
- Butter
- Creams with the sugar to give the cake richness and a tender crumb.
- Brown sugar
- Adds sweetness and moisture, and helps the cake brown and stay soft.
- Flour
- Provides the structure that holds the batter and fruit together as it bakes.
- Sour cream
- Adds moisture and acidity, which helps the baking soda react and the crumb stay tender.
- Baking soda
- Reacts with the sour cream's acidity to produce gas that helps the cake rise.
- Raisins
- Add chewy sweetness and moisture throughout the cake.
The step that matters
Dredging the fruit with flour. Heavy dried fruit sinks to the bottom of a batter during baking. Tossing it in a little flour helps the pieces grip the batter and stay suspended as the cake sets.
Swap the mace
How well each one fits the dish's main ingredients (sugar, butter, flour, raisin, currant, clove, cream):
- Cinnamonfits better
- Nutmegfits better
- Allspicefits better
- Macethe original
Fit is the average pairing score against sugar, butter, flour, raisin, currant, clove, cream. Candidates are from the same food group and used in at least 100 recipes.
