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 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 your oven to 300°F (150°C).
In a large bowl, cream together the butter and brown sugar.
Add the eggs one at a time, mixing well after each addition.
Stir in the molasses and brandy until combined.
In another bowl, mix the flour, cinnamon, nutmeg, cloves, and mace.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in the chopped raisins, currants, and citron.
Bake
Pour the batter into a greased cake pan.
Bake for 2 hours or until a toothpick inserted in the center comes out clean.

Flour and butter 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
- All-purpose flour
- Provides the structure that holds the dense batter and fruit together as it bakes.
- Unsalted butter
- Creams with the sugar to add tenderness and a rich, moist crumb.
- Brown sugar
- Adds sweetness and moisture, and helps the cake brown as it bakes.
- Eggs
- Bind the batter and give it structure and lift as they set in the oven.
- Molasses
- Adds moisture, dark color and a deep, slightly bitter sweetness.
- Raisins
- Add chewy sweetness and moisture throughout the cake.
The step that matters
Gradually add the dry ingredients to the wet mixture, stirring until just combined.. Overmixing once flour meets liquid develops gluten, which makes the cake tough and dense. Stop stirring as soon as no dry streaks remain.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, butter, egg, molasses, brandy, raisin):
- Vanillafits better
- Figfits better
- Currantthe original
- Applefits about as well
Fit is the average pairing score against flour, sugar, butter, egg, molasses, brandy, raisin. Candidates are from the same food group and used in at least 100 recipes.
