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 No. 2
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
Preheat your oven to 300°F (150°C).
Make the batter
In a large bowl, cream together the butter and dark brown sugar.
Add the eggs one at a time, mixing well after each addition.
Stir in the molasses.
In another bowl, combine the flour, baking soda, and spices.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Fold in the raisins, currants, and citron.
Bake
Pour the batter into a greased loaf pan.
Bake slowly for several hours until a toothpick inserted in the center comes out clean.

Shared aroma: isobutyraldehyde (malty, green).
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
- Butter
- Creaming with sugar traps air and gives the cake a tender, rich texture.
- Eggs
- Add structure and help bind the batter as they set in the oven.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Dark brown sugar
- Adds sweetness, moisture, and a deep molasses-like flavor.
- Baking soda
- Reacts with the molasses's acidity to help the cake rise and brown.
- Raisins
- Add moisture and concentrated sweetness throughout the cake.
The step that matters
Bake slowly for several hours. Long, low heat lets the dense batter cook through evenly without the outside burning before the center sets. Testing the center with a toothpick confirms it is fully baked.
Swap the currant
How well each one fits the dish's main ingredients (sugar, flour, butter, raisin, egg, molasses, clove):
- Vanillafits better
- Figfits better
- Applefits better
- Currantthe original
Fit is the average pairing score against sugar, flour, butter, raisin, egg, molasses, clove. 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.
