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 ↓

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
Line the pans with three layers of paper, buttering only the top layer.
Seed the raisins and tear them into quarters.
Wash and dry the currants, stone the dates, and cut them and the figs into small pieces.
Blanch and chop the almonds, then cut the citron and lemon peel into thin slices and small pieces.
Mix the nuts and fruit (except peel) and dredge with ¼ cup of the flour.
Dredge the citron and lemon peel with flour.
Mix and sift the remaining flour with the spices.
Make the batter
Cream the butter, then add the sugar and beaten egg yolks.
Fold in the stiffly beaten egg whites, lemon juice, and rind; beat thoroughly.
Add the liquid and sifted flour alternately, beating well, then add the fruit.
Put a layer of the mixture into the pan, followed by a layer of the peel; repeat until the pan is two-thirds full, finishing with the cake mixture on top.
Bake
Bake in a slow oven at 300°F (150°C) for 8 to 4 hours.

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 form a tender, rich crumb and adds fat for flavour.
- Eggs
- Egg whites give lift and structure, while yolks add richness and binding to the batter.
- Flour
- Forms the structure that holds the heavy fruit and nuts in the cake.
- Brown sugar
- Adds sweetness and moisture, and helps the cake brown as it bakes.
- Dates
- Add moisture and natural sweetness, keeping the cake soft as it bakes.
- Shelled almonds
- Add texture and richness, and a toasty flavour when baked.
The step that matters
Dredging the fruit and peel with flour. Flour coating helps heavy pieces stay suspended instead of sinking to the bottom of the batter, so the fruit is spread evenly through the cake.
Swap the currant
How well each one fits the dish's main ingredients (butter, raisin, sugar, egg, dates, flour, fig):

- Currantthe original
Fit is the average pairing score against butter, raisin, sugar, egg, dates, flour, fig. Candidates are from the same food group and used in at least 100 recipes.
