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
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the strong coffee and molasses, mixing well.
In a separate bowl, combine the flour, baking soda, cream of tartar, and spices.
Make the batter
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in the raisins, citron, and currants.
Pour the batter into a greased baking pan.
Bake
Bake for 30-40 minutes or until a toothpick inserted in the center comes out clean.

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 give the cake a tender, rich texture.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Sugar
- Adds sweetness and, creamed with butter, helps lighten the crumb.
- Molasses
- Adds moisture, deep sweetness and color to the cake.
- Baking soda
- Reacts with the acidic molasses and coffee to produce gas that makes the cake rise.
- Cream of tartar
- Acidifies the batter, supporting the baking soda's reaction and helping the rise.
The step that matters
Stirring the dry ingredients into the wet mixture. Once flour meets liquid, gluten begins to form. Stirring only until just combined keeps the crumb tender, while overmixing makes the cake tough.
Swap the currant
How well each one fits the dish's main ingredients (butter, coffee, sugar, flour, molasses, raisin, cream):
- Vanillafits better

- Currantthe original
Fit is the average pairing score against butter, coffee, sugar, flour, molasses, raisin, cream. Candidates are from the same food group and used in at least 100 recipes.
