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 ↓
Black Fruit Cake
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.
Prepare the fruit and nuts
Remove the gills from the raisins and cut the raisins.
Wash the currants and dry them thoroughly.
Cut the citron into very thin pieces.
Blanch the almonds and pound the almonds.
Dredge the raisins and currants with flour.
Make the batter
Beat the eggs separately, then mix the beaten eggs together.
Cream the butter and sugar.
Gradually stir in the eggs, fruit, and wine mixed with spices, adding the citron last.
Bake
Pour the mixture into a well-greased pan lined with paper.
Bake in a slow oven at 300°F (150°C) for five hours for a large cake or four hours for a smaller cake.

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 and richness as the cake sets.
- Butter
- Adds fat and tenderness, and creaming it with sugar traps air for a lighter crumb.
- Flour
- Provides the structure that holds the heavy fruit and nuts in the cake.
- Sugar
- Sweetens the cake and helps create a tender texture when creamed with butter.
- Raisins
- Add moisture, chewiness, and natural sweetness throughout the cake.
The step that matters
Adding the citron last. Citron is heavy and can sink to the bottom of a dense batter if mixed too early, so it is folded in at the end to distribute it evenly.
Swap the currant
How well each one fits the dish's main ingredients (raisin, almond, sugar, flour, butter, egg, wine):
- Vanillafits better
- Figfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against raisin, almond, sugar, flour, butter, egg, wine. Candidates are from the same food group and used in at least 100 recipes.
