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 ↓
Coffee 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 the batter
Preheat the oven to 350°F (175°C).
Cream the butter and brown sugar together until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the molasses and cold coffee.
In a separate bowl, combine the flour, baking powder, cinnamon, and cloves.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Fold in the chopped raisins.
Bake
Pour the batter into a greased loaf pan and bake for about 60 minutes or until a toothpick comes out clean.

Sugar and cinnamon barely smell alike, yet cooks put them together in 30,779 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 trap air and add richness and tender texture.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Brown sugar
- Adds sweetness, moisture, and a deep caramel flavor.
- Eggs
- Bind the batter and add structure and richness.
- Molasses
- Adds moisture, dark color, and a robust sweet flavor.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
The step that matters
Adding the dry ingredients to the wet mixture. Mixing only until just combined keeps the batter tender. Overmixing develops gluten in the flour, which can make the cake tough and dense.
Swap the raisin
How well each one fits the dish's main ingredients (butter, flour, sugar, coffee, molasses, cinnamon, egg):
- Raisinthe original
- Vanillafits about as well
- Figfits less well
- Blueberryfits less well
Fit is the average pairing score against butter, flour, sugar, coffee, molasses, cinnamon, egg. 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.
