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 ↓

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.
Make the batter
Preheat the oven to 300°F (150°C).
In a large bowl, cream together the sugar and butter until light and fluffy.
Add the flour and mix well.
In a separate bowl, beat the eggs and then add them to the mixture.
Stir in the currants, raisins, citron, almonds, orange peel, cloves, nutmeg, and cinnamon.
Dissolve the baking soda in a little water and add it along with the alum to the mixture.
Pour in the brandy, port wine, and molasses, and mix until combined.
Bake and age
Transfer the batter to a greased cake pan and bake for 4 hours.
Let the cake cool, then wrap it and store it for at least 6 weeks before using.
Once a week, give the cake a brandy bath to keep it moist.

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 trap air and add richness and tender texture.
- Eggs
- Bind the batter and add structure as they set in the oven.
- Flour
- Forms the structure that holds the dense batter together as it bakes.
- Baking soda
- Reacts with the acidic molasses to lighten the batter and aid browning.
- Molasses
- Adds moisture, dark color, and a deep, slightly acidic sweetness.
- Currants
- Add chewy fruitiness and moisture throughout the cake.
The step that matters
Baking soda with alum. Baking soda needs an acid to react and lift the batter; the acidic molasses and alum supply it. Dissolve the soda fully in water first so it mixes evenly and does not leave bitter, soapy pockets or dense patches in the crumb.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, flour, egg, raisin, almond, orange):
- Vanillafits better
- Figfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against sugar, butter, flour, egg, raisin, almond, orange. 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.
