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 says “a very 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).
Make the batter
In a large bowl, cream together the sugar and butter.
Add the eggs one at a time, mixing well after each addition.
Stir in the flour, baking soda, mace, cinnamon, and nutmeg.
Fold in the raisins, currants, and citron.
Pour the batter into a greased cake pan.
Bake
Bake for 3 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Flour
- Provides the structure that holds the fruit and batter together as the cake sets.
- Butter
- Adds fat and tenderness, and creaming it with sugar traps air for a lighter crumb.
- Sugar
- Sweetens the cake and helps brown the crust during the long bake.
- Raisins
- Add chewy sweetness and moisture throughout the cake.
- Baking soda
- Reacts with the batter's acidity to produce gas that helps the cake rise.
The step that matters
Bake low and slow for 3 hours. A long, low bake lets the dense, fruit-heavy batter cook through without the outside burning before the centre sets. Opening the oven early can cause the cake to sink.
Swap the mace
How well each one fits the dish's main ingredients (sugar, butter, flour, raisin, currant, egg, nutmeg):
- Cinnamonfits better
- Allspicefits better
- Cardamomfits better
- Macethe original
Fit is the average pairing score against sugar, butter, flour, raisin, currant, egg, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
