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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, mix the flour, brown sugar, ginger, and chopped raisins.
Stir in the melted butter, cream, treacle, and whisked eggs.
Mix the baking soda with the dry ingredients, ensuring no lumps remain.
Add the vinegar to the mixture and stir until combined.
Bake
Pour the batter into a buttered mold or tin.
Bake in the preheated oven for 1.5 to 2.5 hours.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Forms the main structure of the cake as its gluten sets during baking.
- Eggs
- Bind the batter and add structure and richness as they set.
- Baking soda
- Reacts with the acidic vinegar and treacle to release gas that lightens the cake.
- Melted butter
- Adds fat for tenderness and moisture in the finished crumb.
- Treacle
- Adds sweetness, dark colour and moisture, with a deep molasses flavour.
- Brown sugar
- Sweetens the cake and helps keep it moist and browned.
The step that matters
Mixing the baking soda into the dry ingredients. Baking soda must be evenly distributed before liquids are added; lumps leave pockets of bitter residue and uneven rising. It then reacts with the acidic vinegar and treacle to lift the batter.
Swap the ginger
How well each one fits the dish's main ingredients (flour, butter, cream, molasses, sugar, egg, raisin):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits about as well
- Gingerthe original
Fit is the average pairing score against flour, butter, cream, molasses, sugar, egg, raisin. Candidates are from the same food group and used in at least 100 recipes.
