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
Soak the spices in brandy for a little while before mixing.
Make the batter
In a large bowl, cream together the sugar and butter.
Add the eggs one at a time, mixing well after each addition.
Stir in the flour, currants, raisins, citron, molasses, and soaked spices.
Bake
Pour the batter into a greased cake pan.
Bake at 300°F (150°C) for four hours.

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
- Bind the batter and add structure as the cake sets during baking.
- Butter
- Adds fat and richness, and creaming it with sugar traps air for a tender crumb.
- Flour
- Forms the structure that holds the dense fruit and batter together.
- Sugar
- Sweetens the cake and helps create a tender texture when creamed with butter.
- Molasses
- Adds moisture, dark color, and a deep, slightly bitter sweetness.
- Currants
- Provide moisture, chewiness, and concentrated fruit sweetness throughout the cake.
The step that matters
Baking low and slow for four hours. A long, low bake at 300°F lets the heavy, fruit-filled batter cook through to the center without the outside burning. Too high a heat would set the crust before the interior is done.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, flour, egg, raisin, brandy, molasses):
- Vanillafits better
- Figfits better
- Currantthe original
- Applefits about as well
Fit is the average pairing score against sugar, butter, flour, egg, raisin, brandy, molasses. Candidates are from the same food group and used in at least 100 recipes.
