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 ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the lemon and orange juice and zest.
In a separate bowl, combine the flour, allspice, cloves, and cinnamon.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Fold in the prunes, raisins, currants, cherries, citron, and figs.
Bake
Pour the batter into a greased cake pan and smooth the top.
Bake for 1.5 to 2 hours, or until a toothpick inserted in the center comes out clean.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour 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 to trap air, giving the cake a tender, rich crumb.
- Eggs
- Bind the batter and add structure and richness as the cake sets in the oven.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Sugar
- Sweetens the cake and helps create a light texture when creamed with butter.
- Raisins
- Add moisture and concentrated sweetness to the dense fruit cake.
- Currants
- Add moisture, chewiness and tart fruit flavour throughout the cake.
The step that matters
Gradually add the dry ingredients to the wet mixture, mixing until just combined.. Adding flour in portions and mixing only until combined keeps the batter smooth and limits gluten development, which would otherwise make the cake tough.
Swap the currant

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