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 ↓
Christmas Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and sugar together until light and fluffy.
Beat the egg yolks and whites separately until very light.
Gradually add the flour to the butter and sugar mixture, alternating with the egg yolks and whites.
Stir in the ground mace, ground cinnamon, and molasses.
Gently fold in the chopped raisins, currants, citron, pounded almonds, candied orange peel, and candied lemon peel.
Add the brandy and mix lightly.
Bake
Pour the batter into a prepared cake pan.
Bake in a moderate oven at 350°F (175°C) for four hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, giving the cake a tender, rich crumb.
- Eggs
- Provide structure and lift when the whites are beaten separately and folded in.
- All-purpose flour
- Forms the cake's main structure as it sets in the oven.
- Molasses
- Adds moisture, dark color, and a deep sweetness that promotes browning.
- Almonds
- Add richness, body, and a nutty flavor to the crumb.
- Raisins
- Add moisture and chewy sweetness throughout the cake.
The step that matters
Beating the egg yolks and whites separately. Whipping the whites until very light traps air that helps the cake rise. Folding them in gently keeps that air in the batter, so the cake stays light despite its heavy fruit and nut load.
Swap the mace
How well each one fits the dish's main ingredients (butter, sugar, egg, flour, cinnamon, molasses, raisin):
- Nutmegfits better
- Cardamomfits better
- Allspicefits better
- Macethe original
Fit is the average pairing score against butter, sugar, egg, flour, cinnamon, molasses, raisin. Candidates are from the same food group and used in at least 100 recipes.
