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 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat your oven to 350°F (175°C).
In a bowl, cream together the sugar and butter.
Add the eggs and sour cream, mixing well.
Dissolve the baking soda in a small amount of water and add it to the mixture.
Prepare the fruit
In a separate pot, cook the raisins, currants, and citron in a little water until softened.
Before they cool completely, dredge the fruits with flour to prevent sinking.
Make the batter and bake
Gradually stir in the flour until the dough is stiff enough for a spoon to stand in it.
Fold in the floured fruits, cinnamon, cloves, and grated nutmeg.
Pour the batter into a greased cake pan and bake for about 1 hour or until a toothpick comes out clean.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 texture.
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Flour
- Forms the cake's structure once stirred in, stiffening the batter.
- Baking soda
- Reacts with the acidic sour cream to produce gas that helps the cake rise.
- Sour cream
- Adds moisture and acidity, tenderising the crumb and activating the baking soda.
- Raisins
- Provide chewy pockets of fruit sweetness throughout the cake.
The step that matters
Dredge the fruits with flour before they cool. Flour coats the moist, sticky fruit so it grips the batter and is less likely to sink to the bottom of the cake during baking.
Swap the currant

- Currantthe original
Fit is the average pairing score against sugar, butter, egg, cream, flour, raisin, cinnamon. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
