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 ↓

Ingredients
Directions
The book says “a moderate oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 300°F (150°C).
Make the batter
Cream the butter and sugar together until light and fluffy.
Beat in the eggs one at a time.
Gradually add the flour, mixing well.
Fold in the currants, raisins, and citron.
Stir in the brandy, molasses, and spices.
Bake
Pour the batter into a greased cake pan.
Bake for about 2 to 3 hours or until a toothpick comes out clean.

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
- Creamed with sugar to trap air, giving a tender, rich crumb.
- Flour
- Forms the cake's structure once the batter sets in the oven.
- Sugar
- Creamed with butter for lightness and adds sweetness and tender browning.
- Molasses
- Adds moisture, deep sweetness and a darker color to the cake.
- Currants
- Dried fruit that adds chewy texture and concentrated sweetness throughout the cake.
The step that matters
Creaming the butter and sugar. Beating them until light and fluffy traps air that helps the cake rise and keeps the crumb tender. Under-creaming leaves a dense cake, while over-beating in the flour later can toughen it.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, raisin, egg, flour, brandy, molasses):
- Vanillafits better
- Figfits better
- Currantthe original
- Applefits about as well
Fit is the average pairing score against sugar, butter, raisin, egg, flour, brandy, molasses. Candidates are from the same food group and used in at least 100 recipes.
