Why it works: Allspice and cinnamon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 5,536 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Plum Cake
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 400°F (200°C).
In a large bowl, cream together the butter and molasses.
Add the sweet milk and beaten eggs, mixing well.
Dissolve the baking soda in a little hot water and add it to the mixture.
Stir in the mace, allspice, and cinnamon.
Gradually add flour until the batter is stiff but can be stirred easily.
Beat the batter well until light.
Fold in the raisins, currants, and citron.
Bake
Pour the batter into a greased cake pan and bake for about 1 hour or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with molasses to give the cake richness and a tender crumb.
- Molasses
- Adds sweetness, dark color, and moisture to the cake.
- Eggs
- Bind the batter and add structure as the cake sets.
- Baking soda
- Reacts with the molasses to produce gas that helps the cake rise.
- Flour
- Forms the structure of the cake, setting it as it bakes.
- Raisins
- Add chewy texture and sweetness throughout the cake.
The step that matters
Gradually adding the flour. Adding flour in small amounts while stirring keeps the batter smooth and stiff enough to hold the fruit. Too much flour at once can make the cake dense or tough. The batter should be stiff but still easy to stir.
Swap the mace
How well each one fits the dish's main ingredients (butter, molasses, milk, egg, allspice, cinnamon, brandy):
- Nutmegfits better
- Clovefits better
- Cardamomfits better
- Macethe original
Fit is the average pairing score against butter, molasses, milk, egg, allspice, cinnamon, brandy. Candidates are from the same food group and used in at least 100 recipes.
