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 moderate 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 until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Sift together the flour, baking soda, nutmeg, and spices, then gradually add to the egg mixture.
Dissolve the baking soda in a small amount of water and add it just before mixing in the fruit.
Fold in the raisins, currants, citron, orange, walnuts, prunes, molasses, and currant jelly.
Bake
Pour the batter into a greased cake pan.
Bake for four hours, starting with a warm oven, then gradually increasing the heat for two hours, and finally baking in a moderate oven until done.

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
- Eggs
- Bind the batter and add structure as they set during baking.
- Butter
- Adds richness and tenderness through fat coating the flour and creaming air into the batter.
- Flour
- Forms the structure that holds the dense batter and fruit together as it bakes.
- Sugar
- Sweetens the cake and helps create a light, creamed texture with the butter.
- Baking soda
- Reacts with the acidic molasses and jelly to help the cake rise and darken.
- Molasses
- Adds moisture, dark colour and a deep, slightly acidic sweetness.
The step that matters
Adding the baking soda just before the fruit. Baking soda starts reacting as soon as it meets acid, so delaying its addition until just before baking keeps the rise from fading before the cake sets.
Swap the currant

Fit is the average pairing score against egg, sugar, flour, butter, raisin, orange, walnut. Candidates are from the same food group and used in at least 100 recipes.
