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

  1. Preheat the oven to 350°F (175°C).

  2. In a large bowl, mix together the molasses, coffee, brown sugar, and butter until well combined.

  3. Add the eggs one at a time, mixing well after each addition.

  4. In another bowl, combine the flour and baking soda.

  5. Gradually add the flour mixture to the wet ingredients, mixing until just combined.

  6. Fold in the raisins, currants, citron, cinnamon, cloves, and nutmeg.

Bake

  1. Pour the batter into a greased baking pan and bake for about 45-50 minutes or until a toothpick comes out clean.

The flavor team

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
Forms the structure that holds the cake together as it bakes.
Eggs
Add structure and richness, binding the batter as they set in the oven.
Baking soda
Reacts with the acidic molasses and coffee to help the cake rise.
Molasses
Adds moisture, dark color, and a deep sweetness with a slight acidity.
Butter
Adds fat for tenderness and rich flavor.
Raisins
Add chewy texture and concentrated sweetness throughout the cake.

The step that matters

Gradually add the flour mixture. Adding flour in portions and mixing only 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 (molasses, coffee, sugar, butter, egg, flour, raisin):

  1. Vanillafits better
  2. Figfits better
  3. Applefits about as well
  4. Currantthe original

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