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 ↓
Black 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.
Make the batter
Preheat the oven to 350°F (175°C).
In a large bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the molasses and sour cream.
In a separate bowl, combine the flour, baking soda, cinnamon, allspice, and cloves.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Fold in the currants, raisins, citron, and chopped figs.
Bake
Pour the batter into a greased cake pan.
Bake for 2 to 3 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
- Eggs
- Bind the batter and add structure as they set during baking.
- Butter
- Creamed with sugar to trap air, giving the cake a tender crumb and rich flavor.
- Flour
- Forms the main structure of the cake as its proteins set in the oven.
- Baking soda
- Reacts with the acidic molasses and sour cream to help the cake rise.
- Molasses
- Adds moisture, dark color, and a deep, slightly acidic sweetness.
- Sour cream
- Adds moisture and acidity that tenderizes the crumb and reacts with baking soda.
The step that matters
Adding the dry ingredients. Mixing only until just combined keeps gluten development low, so the cake stays tender rather than tough and dense.
Swap the currant
How well each one fits the dish's main ingredients (flour, raisin, sugar, fig, butter, egg, molasses):
- Vanillafits better
- Datesfits better
- Applefits better
- Currantthe original
Fit is the average pairing score against flour, raisin, sugar, fig, butter, egg, molasses. 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.
