Why it works: Raisin and flour 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 ↓
Christmas Cake Recipe
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.
Prepare
Preheat the oven to 300°F (150°C).
In a bowl, mix the raisins, currants, peel, dates, yellow sugar, almonds, flour, mace, cinnamon, and nutmeg.
Make the batter
In another bowl, cream the butter and add the eggs one at a time, mixing well.
Dissolve the baking soda in a little hot water and add it to the mixture just before adding the fruit.
Combine the fruit mixture with the butter and egg mixture, stirring until well combined.
Bake
Pour the batter into a prepared cake pan.
Bake for three hours or more, until a toothpick inserted in the center comes out clean.

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.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Flour
- Provides the structure that holds the fruit and batter together as the cake sets.
- Baking soda
- Reacts with the batter to produce gas that helps the cake rise.
- Yellow sugar
- Adds sweetness and moisture, and helps the crust brown during baking.
- Raisins
- Add sweetness and moisture to the dense, fruit-packed crumb.
The step that matters
Bake until the center is fully set. A dense batter packed with fruit and sugar needs long, low heat so the center cooks through before the outside over-browns. Testing the center with a toothpick confirms it is set.
Swap the mace
How well each one fits the dish's main ingredients (raisin, currant, dates, sugar, almond, flour, cinnamon):
- Nutmegfits better
- Cardamomfits better
- Allspicefits better
- Macethe original
Fit is the average pairing score against raisin, currant, dates, sugar, almond, flour, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
