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 your oven to 350°F (175°C).
In a large bowl, cream the butter and sugar together.
Add the molasses and coffee, mixing well.
In a separate bowl, combine the flour and baking soda.
Gradually add the dry ingredients to the wet mixture, stirring until combined.
Fold in the raisins.
Bake
Pour the batter into a greased baking pan.
Bake for 30-40 minutes or until a toothpick comes out clean.

Flour and butter 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
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Butter
- Adds fat for a tender crumb and rich flavor.
- Sugar
- Sweetens the cake and helps it brown while creaming with butter traps air for lightness.
- Molasses
- Adds moisture, deep sweetness, and a dark color to the crumb.
- Baking soda
- Reacts with the acidic molasses and coffee to produce gas that lifts the batter.
- Coffee
- Adds liquid to hydrate the flour and a subtle roasted aroma that complements the molasses.
The step that matters
Gradually add the dry ingredients to the wet mixture. Adding flour in portions and stirring only until combined keeps gluten development limited, so the cake stays tender rather than tough and dense.
Swap the raisin
How well each one fits the dish's main ingredients (flour, butter, coffee, molasses, sugar):
- Raisinthe original
- Vanillafits about as well
- Figfits less well
- Bananafits less well
Fit is the average pairing score against flour, butter, coffee, molasses, sugar. Candidates are from the same food group and used in at least 100 recipes.
