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 ↓
Rich Fruit Cake
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Preheat the oven to 300°F (150°C).
In a large bowl, cream together the butter and sugar.
Add the flour, molasses, and chopped almonds, and mix well.
Dissolve the baking soda in the milk and add it to the mixture.
Beat in the eggs, one at a time, mixing well after each addition.
Coat the raisins, citron, and currants with flour, then fold them into the batter.
Add the brandy or jelly, nutmeg, cloves, and cinnamon, and mix until combined.
Bake
Pour the batter into a greased cake pan.
Bake for a long time until a toothpick inserted 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 they set in the oven.
- Butter
- Creaming with sugar traps air and gives the cake a tender, rich texture.
- Flour
- Forms the main structure of the cake as the batter sets.
- Baking soda
- Reacts with the molasses and helps the cake rise and lighten.
- Molasses
- Adds moisture, dark color, and a deep sweet flavor.
- Raisins
- Add chewy texture and concentrated sweetness throughout the cake.
The step that matters
Baking long enough at low heat. Dense fruit cakes need a slow, long bake so the center sets fully without the outside burning. Testing with a toothpick confirms the center is cooked through before cooling.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, raisin, molasses, almond, egg):
- Vanillafits better

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