Why it works: Raisin and flour 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 the fruit
Stir the raisins and chop all the fruit together.
Make the batter
In a large bowl, cream together the butter and sugar.
Add the molasses and eggs, mixing well.
In another bowl, combine the flour, baking soda, and spices.
Gradually add the dry ingredients to the wet mixture, stirring until combined.
Fold in the chopped fruit and mix well.
Divide the batter into two greased cake pans.
Bake
Bake for 3 hours or until a toothpick inserted in the center comes out clean.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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 they set during baking.
- Butter
- Adds fat and richness, and helps trap air when creamed with sugar.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
- Flour
- Forms the structure of the cake as its proteins set during baking.
- Baking soda
- Reacts with the acidic molasses to produce gas that lifts the batter.
- Molasses
- Adds moisture, dark color, and a deep, slightly acidic flavor.

How well each one fits the dish's main ingredients (egg, molasses, butter, sugar, raisin, flour, clove):
- Vanillafits better
- Figfits better
- Applefits better
- Currantthe original
Fit is the average pairing score against egg, molasses, butter, sugar, raisin, flour, clove. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
