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 ↓
Fruit Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 350°F (175°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.
Stir in the flour gradually, mixing until just combined.
Add the fruit and flavourings
Fold in the chopped raisins, currants, sliced citron, brandy, and all spices.
Add the vanilla, orange, almond extracts, and lemon juice and rinds.
Bake
Divide the batter into two greased and lined pans.
Bake for 1 hour and 15 minutes 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
- Butter
- Creams with sugar to trap air, giving a light, tender crumb and rich flavour.
- Eggs
- Bind the batter and add structure and richness as the cake sets in the oven.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Raisins
- Add moisture, chewiness and sweetness throughout the dense fruit cake.
- Currants
- Add moisture, tartness and concentrated fruit flavour throughout the cake.
- Brandy
- Adds aroma and flavour and helps keep the cake moist.
The step that matters
Stir in the flour gradually, mixing until just combined.. Overmixing flour after it meets the liquid develops gluten, which can make the cake tough and dense. Mixing only until combined keeps the crumb tender.
Swap the clove
How well each one fits the dish's main ingredients (butter, sugar, flour, egg, raisin, currant, brandy):
- Cinnamonfits better
- Nutmegfits better
- Allspicefits about as well
- Clovethe original
Fit is the average pairing score against butter, sugar, flour, egg, raisin, currant, brandy. Candidates are from the same food group and used in at least 100 recipes.
