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
Wash and dry the currants, seed the raisins, and chop half of the raisins.
Make the batter
In a large bowl, cream together the sugar and butter.
Add the flour, raisins, currants, citron, brown sugar, molasses, baking soda dissolved in coffee, beaten eggs, nutmeg, cinnamon, and allspice. Mix well.
Bake
Pour the batter into a prepared baking pan.
Bake in a slow oven at 300°F (150°C) for 4 hours, placing a pan of water in the oven.

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.

Butter and flour 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
- Eggs
- Bind the batter and add structure as they set during baking.
- Butter
- Creams with sugar to trap air and give a tender, rich crumb.
- Flour
- Forms the main structure that holds the fruit and batter together.
- Baking soda
- Dissolved in coffee, it reacts to help the cake rise and lighten.
- Molasses
- Adds moisture, dark color and a deep sweetness.
- Raisins
- Add moisture, chewy texture and natural sweetness throughout the cake.
The step that matters
Baking low and slow with a pan of water. A long, gentle bake at a low temperature lets the dense, fruity batter cook through without scorching the outside. The water in the oven adds humidity, which keeps the crust from drying out too quickly.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, flour, raisin, molasses, coffee, egg):
- Vanillafits better
- Figfits better
- Applefits about as well
- Currantthe original
Fit is the average pairing score against sugar, butter, flour, raisin, molasses, coffee, egg. Candidates are from the same food group and used in at least 100 recipes.
