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 ↓
Dark Raisin 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. 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
Preheat your oven to 350°F (175°C).
Make the batter
In a large bowl, cream together the butter and sugar.
Add the molasses, sour milk, and eggs, mixing well.
In another bowl, combine the flour, baking soda, and spices.
Gradually add the dry ingredients to the wet mixture, stirring until combined.
Fold in the chopped raisins and citron.
Bake
Pour the batter into a greased cake pan and bake for about 30-40 minutes, or until a toothpick comes out clean.

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
- Eggs
- Bind the batter and add structure as they set during baking.
- Baking soda
- Reacts with the acidic sour milk and molasses to produce gas that lifts the cake.
- Flour
- Forms the main structure of the cake as its proteins set in the oven.
- Butter
- Creams with the sugar to trap air and adds richness and tenderness.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
- Molasses
- Adds moisture, deep sweetness, and a darker color to the cake.
The step that matters
Adding the baking soda with the acidic wet ingredients. Baking soda needs an acid, such as the sour milk and molasses here, to release gas. If the batter sits too long before baking, or the soda is not evenly mixed, the cake may rise poorly or have uneven texture.
Swap the raisin
How well each one fits the dish's main ingredients (molasses, butter, milk, sugar, egg, flour):
- Raisinthe original
- Vanillafits about as well
- Figfits less well
- Peachfits less well
Fit is the average pairing score against molasses, butter, milk, sugar, egg, flour. 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.
