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 ↓
Black 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
Preheat the oven to 350°F (175°C).
Beat the butter and sugar together until creamy.
Whisk the eggs until frothy.
Mix and bake
Gradually add the flour and mix in the fruit.
Pour the mixture into a prepared baking pan.
Bake for 2 hours.

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
- Butter
- Creamed with sugar, it traps air and adds richness and tender texture.
- Eggs
- Whisked eggs add structure and help bind the batter together.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Sugar
- Sweetens the cake and helps create a creamy, aerated batter when beaten with butter.
- Raisins
- Add moisture, chewiness and concentrated fruit sweetness throughout the cake.
- Currants
- Add moisture and tart fruit flavor distributed through the batter.
The step that matters
Beating butter and sugar until creamy. Beating incorporates air into the fat, creating small bubbles that help the cake rise and give it a lighter crumb. Under-beating leaves a denser cake.
Swap the mace
How well each one fits the dish's main ingredients (flour, butter, sugar, raisin, currant, egg, clove):
- Cinnamonfits better
- Nutmegfits better
- Allspicefits better
- Macethe original
Fit is the average pairing score against flour, butter, sugar, raisin, currant, egg, clove. Candidates are from the same food group and used in at least 100 recipes.
