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 Wedding 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.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a large bowl, cream the butter and brown sugar together. Add the molasses and sweet milk, mixing well.
In a separate bowl, sift the flour with the baking powder. Gradually add the flour mixture to the wet ingredients.
Incorporate the beaten eggs into the batter. Fold in the raisins, currants, chopped citron, allspice, cinnamon, and nutmeg.
Bake
Pour the batter into a greased cake pan.
Bake for about 1 hour, checking to avoid burning.

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
- Butter
- Creams with sugar to add richness and a tender crumb.
- Brown sugar
- Adds sweetness and moisture, and helps the cake brown.
- Molasses
- Adds dark color, moisture and a deep, slightly bitter sweetness.
- Flour
- Forms the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Eggs
- Bind the batter and add structure and richness as they set.
The step that matters
Folding in the fruit. Heavy fruit can sink to the bottom of a thick batter if overmixed or added carelessly. Folding gently keeps the fruit spread evenly through the cake.
Swap the currant
How well each one fits the dish's main ingredients (butter, sugar, molasses, milk, flour, egg, raisin):
- Vanillafits better
- Figfits better
- Datesfits about as well
- Currantthe original
Fit is the average pairing score against butter, sugar, molasses, milk, flour, egg, raisin. 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.
