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 the batter

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

  2. In a large bowl, cream the butter and sugar together until light and fluffy.

  3. Add the molasses and liquid coffee, mixing well.

  4. In another bowl, combine the flour, baking powder (or baking soda), and spices.

  5. Gradually add the dry ingredients to the wet mixture, stirring until just combined.

  6. Fold in the eggs, raisins, and currants until evenly distributed.

Bake

  1. Pour the batter into a greased baking pan and smooth the top.

  2. Bake for about 45-50 minutes, or 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

Flour
Forms the main structure of the cake as the batter sets in the oven.
Eggs
Add structure and richness, helping the batter bind and set during baking.
Butter
Adds fat for tenderness and flavor, and helps trap air when creamed with sugar.
Sugar
Sweetens the cake and, creamed with butter, helps give a light, fluffy texture.
Baking powder
Releases gas in the batter to make the cake rise; used here as an alternative to baking soda.
Molasses
Adds moisture, deep sweetness, and a dark color to the cake.

The step that matters

Gradually add the dry ingredients to the wet mixture, stirring until just combined.. Overmixing once flour meets liquid develops gluten, which can make the cake tough and dense. Stirring only until combined keeps the crumb tender.

Swap the currant

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

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

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