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 ↓
Fruit Cake
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Preheat your oven to 300°F (150°C).
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the molasses and currant juice.
In another bowl, combine the flour, baking soda, mace, nutmeg, cinnamon, cloves, and ginger.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Fold in the raisins, currants, and citron.
Bake
Pour the batter into prepared cake pans and smooth the top.
Bake for several hours, checking for doneness with a toothpick.

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 trap air and add richness and tenderness.
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Flour
- Forms the main structure of the cake once it bakes and sets.
- Baking soda
- Reacts with the molasses acidity to help the cake rise and lighten.
- Molasses
- Adds moisture, deep sweetness, and a darker color to the crumb.
- Raisins
- Add chewy texture and concentrated sweetness throughout the cake.
The step that matters
Baking low and slow until fully done. A dense, fruit-heavy batter conducts heat slowly, so the centre can stay raw while the edges over-brown. Low heat for a long time lets the heat reach the middle gently, and a toothpick test confirms the centre has set before cooling.
Swap the mace
How well each one fits the dish's main ingredients (flour, butter, sugar, raisin, currant, egg, nutmeg):
- Cinnamonfits better
- Allspicefits better
- Cardamomfits better
- Macethe original
Fit is the average pairing score against flour, butter, sugar, raisin, currant, egg, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
