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).
Make the batter
In a large bowl, cream together brown sugar, molasses, and butter.
Add warm coffee and egg, mixing well.
In another bowl, combine flour, allspice, cloves, cinnamon, mace, baking soda, and cream of tartar.
Gradually add dry ingredients to wet mixture, stirring until combined.
Fold in raisins and currants.
Grate nutmeg into batter and mix well.
Bake
Pour batter into greased baking pan and bake for about 45‑50 minutes or until a toothpick comes out clean.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Flour
- Provides the structure that holds the dense batter together as it bakes.
- Butter
- Adds richness and tenderness through fat that coats the flour.
- Molasses
- Adds moisture, dark color, and deep sweetness to the cake.
- Baking soda
- Reacts with the acidic molasses and cream of tartar to produce gas that lifts the batter.
- Cream of tartar
- Acidifies the batter, helping the baking soda react and leaving a lighter crumb.
- Egg
- Binds the batter and adds structure and moisture.
The step that matters
Adding the dry ingredients to the wet mixture. Stirring gently until just combined keeps gluten development limited, so the cake stays tender rather than tough and dense.
Swap the currant
How well each one fits the dish's main ingredients (sugar, molasses, butter, flour, coffee, egg, raisin):
- Vanillafits better
- Figfits better
- Applefits about as well
- Currantthe original
Fit is the average pairing score against sugar, molasses, butter, flour, coffee, egg, raisin. Candidates are from the same food group and used in at least 100 recipes.
