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 into small pieces.
Blanch and chop the almonds.
Cut the citron and lemon peel into thin slices and then into 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.
Add the sugar and beaten egg yolks.
Fold in the beaten egg whites, lemon juice, and rind.
Add the liquid and sifted flour alternately, beating well.
Fold in the fruit.
Bake
Put a layer of the mixture into the pan.
Put a layer of the peel.
Repeat until the pan is two-thirds full.
Finish with the cake mixture on top.
Bake in a slow oven at 300°F (150°C) for 3 to 4 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks and whites add structure and richness as the batter sets in the oven.
- Butter
- Creamed with sugar, it traps air and gives the cake a tender, rich crumb.
- Flour
- Sets the batter's structure so the heavy fruit stays suspended rather than sinking.
- Brown sugar
- Adds sweetness and moisture, and helps the cake brown during the long bake.
- Dates
- Add moisture and natural sweetness, keeping the cake soft after baking.
- Almonds
- Add fat, texture and a nutty flavor that complements the spices.
The step that matters
Dredge the fruit and peel in flour before folding them in. Flour coats the pieces so they bind to the batter and are less likely to sink to the bottom of the pan during the long bake.
Swap the currant
How well each one fits the dish's main ingredients (butter, raisin, sugar, egg, dates, flour, almond):
- Figfits better

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