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 ↓
Fruit Cake
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the fruit and dry ingredients
Chop the currants, citron, and raisins.
Mix the chopped fruit with 1 cup of flour.
Sift the remaining flour with baking soda, cinnamon, and salt.
Make the batter
Cream the butter with brown sugar, molasses, and beaten eggs.
Add the flour mixture, fruit, and coffee to the creamed mixture.
Stir well and pour into a greased baking pan.
Bake
Bake in a moderate oven at 350°F (175°C) for 1 hour.

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.

Cinnamon and sugar barely smell alike, yet cooks put them together in 30,779 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 and richness as they set in the oven.
- Butter
- Adds fat for tenderness and richness, and carries flavor through the batter.
- All-purpose flour
- Provides the structure that holds the fruit and batter together as it bakes.
- Baking soda
- Reacts with the molasses and acidic ingredients to lift the batter and help it rise.
- Molasses
- Adds moisture, deep flavor, and a darker color through browning.
- Brown sugar
- Sweetens the batter and helps keep the cake moist and tender.
The step that matters
Stir well and pour into a greased baking pan. Thorough mixing spreads the fruit and leavening evenly, and a well-greased pan keeps the dense, sticky batter from sticking and tearing when the cake is removed.
Swap the currant
How well each one fits the dish's main ingredients (raisin, flour, cinnamon, butter, sugar, molasses, egg):
- Vanillafits better
- Figfits better
- Datesfits better
- Currantthe original
Fit is the average pairing score against raisin, flour, cinnamon, butter, sugar, molasses, egg. Candidates are from the same food group and used in at least 100 recipes.
