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 ↓
A Magnificent Christmas Cake
Ingredients
Directions
The book says “a steady oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the batter
Preheat the oven to 300°F (150°C).
In a large bowl, mix flour and baking powder.
In another bowl, cream butter and sugar until light.
Add eggs one at a time, mixing well after each addition.
Stir in the milk, then add the flour mixture gradually.
Fold in raisins, currants, and citron.
Add lemon, nutmeg, allspice, and salt to taste.
Bake and finish
Pour the batter into a greased cake pan.
Bake for 4 to 5 hours until a toothpick comes out clean.
Let cool, then ice and decorate with holly.

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 cake together as it bakes.
- Butter
- Adds richness and tenderness, and carries flavor through the batter.
- Eggs
- Bind the batter and add structure and richness as they set.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Sugar
- Sweetens the cake and helps it brown and stay moist.
- Raisins
- Add chewy texture and concentrated fruit sweetness throughout the cake.
The step that matters
Long, low baking until a toothpick comes out clean. With a dense batter full of fruit, the centre sets slowly. Pulling the cake too early leaves it gummy, while the low oven heat helps it cook through without scorching the outside.
Swap the currant
How well each one fits the dish's main ingredients (flour, sugar, raisin, butter, egg, milk, lemon):

Fit is the average pairing score against flour, sugar, raisin, butter, egg, milk, lemon. Candidates are from the same food group and used in at least 100 recipes.
