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.
Prepare the batter
Preheat the oven to 350°F (175°C).
In a large bowl, cream together the butter and brown sugar.
Add the eggs, molasses, and cold coffee; mix well.
In another bowl, combine the flour, baking soda, baking powder, cinnamon, cloves, and nutmeg.
Dredge the raisins and citron in a little flour, then fold them into the batter.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Bake
Pour the batter into a greased cake pan and bake for 1 hour.

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.

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
- Eggs
- Bind the batter and add structure as they set in the oven.
- Butter
- Adds richness and tenderness, and helps trap air when creamed with sugar.
- Brown sugar
- Adds sweetness and moisture, and contributes to a soft crumb and browning.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking soda
- Reacts with the acidic molasses and coffee to produce gas that lifts the cake.
- Orleans molasses
- Adds moisture, deep flavor, and browning to the cake.
The step that matters
Stirring in the dry ingredients. Once flour meets liquid, gluten begins to form. Mixing only until combined keeps the cake tender rather than tough and dense.
Swap the raisin
How well each one fits the dish's main ingredients (egg, sugar, molasses, butter, coffee, flour, cinnamon):
- Raisinthe original
- Vanillafits about as well
- Figfits less well
- Blueberryfits less well
Fit is the average pairing score against egg, sugar, molasses, butter, coffee, flour, cinnamon. 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.
