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 ↓
Fruit Cake
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 the batter
Preheat the oven to 300°F (150°C).
Cream together the sugar and butter until light and fluffy.
Beat in the eggs one at a time, mixing well after each addition.
Stir in the sour cream and baking soda until well combined.
Gradually add the flour, mixing until just incorporated.
Fold in the raisins, currants, and citron.
Add the grated nutmeg, cinnamon, mixed spice, and cloves, and mix well.
Bake
Pour the batter into a greased cake pan.
Bake for 2 hours or 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
- Butter
- Creams with sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Add structure and set the batter as they bake, binding the fruit.
- Flour
- Forms the main structure of the cake once its proteins set in the oven.
- Baking soda
- Reacts with the sour cream's acidity to produce gas that helps the cake rise.
- Sour cream
- Adds moisture and acidity, tenderizing the crumb and activating the baking soda.
- Raisins
- Add moisture and chewy sweetness throughout the cake.
The step that matters
Adding the flour. Mixing flour only until just incorporated keeps gluten development limited, so the cake stays tender rather than tough and dense.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, flour, egg, cream, raisin, nutmeg):
- Vanillafits better

- Currantthe original
Fit is the average pairing score against sugar, butter, flour, egg, cream, raisin, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
