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 ↓
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 oven to 350°F (175°C).
In a large bowl, mix coffee (or coffee extract), molasses, butter, and sugar until well combined.
Add raisins, currants, flour, nutmeg, cinnamon extract, cloves, and eggs; mix until smooth.
Dissolve baking soda in a small amount of hot water and add to batter; stir well.
Bake
Pour batter into greased baking pan and bake for about 45‑50 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
- Eggs
- Bind the batter and add structure as the cake sets in the oven.
- Baking soda
- Reacts with the molasses acidity to lighten the batter and help it rise.
- Flour
- Forms the main structure that holds the cake together as it bakes.
- Butter
- Adds fat for tenderness and richness in the crumb.
- Molasses
- Adds moisture, dark color, and deep sweetness with a slight acidity.
- Sugar
- Sweetens the cake and helps give it a tender texture and browning.
The step that matters
Dissolving the baking soda. Baking soda needs an acid, such as the molasses here, to react and leaven the batter. Dissolving it fully in hot water before adding it spreads the reaction evenly so the cake rises without pockets or bitter spots.
Swap the currant
How well each one fits the dish's main ingredients (coffee, molasses, butter, sugar, raisin, flour, nutmeg):
- Vanillafits better
- Figfits better
- Orangefits better
- Currantthe original
Fit is the average pairing score against coffee, molasses, butter, sugar, raisin, flour, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
