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
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, beat together the sugar, butter, and eggs until well combined.
Add the sweet milk, raisins, citron, currants, and spices.
Sift in the flour with the baking powder and mix until just combined.
Bake
Pour the batter into a prepared cake pan and bake for 4 to 5 hours.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure that holds the dense batter together as it bakes.
- Eggs
- Bind the batter and add structure and richness as they set.
- Butter
- Adds fat for tenderness and a rich texture.
- Sugar
- Sweetens the cake and helps it brown during the long bake.
- Baking powder
- Releases gas that helps the cake rise and lighten.
- Raisins
- Add sweetness, chewy texture and moisture to the fruit cake.
The step that matters
Mix the flour in until just combined. Once flour meets liquid, gluten begins to form; overmixing makes the cake tough and dense, so stop as soon as no dry flour streaks remain.
Swap the clove
How well each one fits the dish's main ingredients (sugar, raisin, currant, flour, butter, egg, milk):
- Cinnamonfits better
- Nutmegfits better
- Allspicefits about as well
- Clovethe original
Fit is the average pairing score against sugar, raisin, currant, flour, butter, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
