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 ↓

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and brown sugar together until light and fluffy.
Add the molasses and eggs, mixing well.
Stir in the buttermilk and baking soda.
Gradually add the flour, mixing until just combined.
Fold in the raisins, currants, and spices.
Bake
Pour the batter into a greased cake pan and bake for 30-40 minutes or until a toothpick comes out clean.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and add richness and a tender crumb.
- Eggs
- Bind the batter and add structure and moisture as the cake sets.
- Baking soda
- Reacts with the acidic buttermilk and molasses to release gas that helps the cake rise.
- All-purpose flour
- Forms the main structure of the cake once its proteins set in the oven.
- Molasses
- Adds moisture, deep sweetness, and a dark color with a slight acidity.
- Buttermilk
- Adds moisture and acidity that activates the baking soda and tenderizes the crumb.
The step that matters
Adding the flour. Mixing flour 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 (butter, sugar, molasses, egg, buttermilk, flour, raisin):
- Vanillafits better
- Figfits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against butter, sugar, molasses, egg, buttermilk, flour, 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.
