Why it works: Almond and flour are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 8,673 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
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
Preheat the oven to 300°F (150°C).
Line a pan 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 fruit (except peel) and dredge with 4 tablespoons of 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 brown sugar and the beaten egg yolk.
Fold in the stiffly beaten egg white, lemon juice, and grated lemon rind; beat thoroughly.
Add the liquid and sifted flour alternately, beating well.
Finally, add the fruit and nuts.
Bake
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 for 2 to 3 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to give the cake a tender, rich crumb.
- Egg
- Beaten whites add lift and the yolk adds richness and structure to the batter.
- Flour
- Provides the structure that holds the cake together around the fruit.
- Brown sugar
- Adds sweetness, moisture and a deeper caramel flavour.
- Dates
- Add moisture and natural sweetness to the dense fruit cake.
- Raisins
- Add chewy texture and concentrated sweetness throughout the cake.
The step that matters
Baking low and slow. A long, gentle bake at a low temperature lets the dense batter cook through to the centre without the fruit-heavy outside burning.
Swap the dates
How well each one fits the dish's main ingredients (butter, sugar, almond, egg, lemon, flour, coffee):
- Vanillafits better

Fit is the average pairing score against butter, sugar, almond, egg, lemon, flour, coffee. Candidates are from the same food group and used in at least 100 recipes.
