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.

Make the batter

  1. Cream together the sugar and butter until light and fluffy.

  2. Add the molasses and strong coffee, mixing well.

  3. Beat in the eggs one at a time until fully incorporated.

  4. In a separate bowl, combine the flour and baking powder.

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

  6. Fold in the raisins, currants, sliced citron, and spices.

Bake

  1. Pour the batter into a greased baking pan.

  2. Bake at 350°F (175°C) until a toothpick inserted in the center 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

Butter
Creams with the sugar to trap air, giving a light, tender crumb and rich flavor.
All-purpose flour
Provides the structure that sets the cake as the batter bakes.
Eggs
Add structure and richness, and help bind the batter together.
Molasses
Adds moisture, dark color, and a deep, slightly bitter sweetness.
Baking powder
Releases gas during baking so the cake rises and becomes lighter.
Granulated sugar
Sweetens the cake and helps create a tender texture when creamed with butter.

The step that matters

Gradually add the flour mixture. Mixing flour into the batter only until combined keeps gluten development limited, so the cake stays tender rather than tough.

Swap the currant

How well each one fits the dish's main ingredients (sugar, butter, molasses, coffee, egg, flour, raisin):

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

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