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 ↓
Superior Fruit Cake
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
In a small pot, combine molasses and spices; steep gently for 20-30 minutes without boiling.
Beat the eggs until very light.
Butter a sheet of paper and line a pan with it.
Make the batter
Gradually stir in the fruit, which should be cut into pieces and well floured.
Dissolve baking soda in water and add to the mixture.
If necessary, add more flour after the fruit is mixed in.
Pour the cake mixture into the prepared pan.
Bake and finish
Bake for 3 to 4 hours, depending on the thickness of the loaves.
Allow the cake to cool gradually in the oven.
Ice the cake once it is cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten until light, they add structure and lift to the batter.
- Flour
- Provides the structure that holds the fruit and batter together as the cake sets.
- Butter
- Adds richness and tenderness through fat in the batter.
- Sugar
- Adds sweetness and helps the crumb brown during baking.
- Molasses
- Adds moisture, dark color, and a deep sweetness to the cake.
- Baking soda
- Reacts with the molasses to help the cake rise and lighten.
The step that matters
Baking long and slow with a gradual cool. A dense fruit cake needs a long, low bake so the centre sets without the outside burning. Cooling gradually in the oven keeps the cake from cracking or sinking as it firms.
Swap the currant
How well each one fits the dish's main ingredients (flour, butter, sugar, raisin, almond, pineapple, egg):
- Vanillafits better

- Currantthe original
Fit is the average pairing score against flour, butter, sugar, raisin, almond, pineapple, egg. Candidates are from the same food group and used in at least 100 recipes.
