Spice Cake

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 ↓

Spice 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 the oven to 350°F (175°C).

  2. In a bowl, mix together brown sugar, molasses, and sour milk with baking soda until well combined.

  3. Cream the butter and add it to the mixture.

  4. Stir in spices to taste.

  5. Gradually add the flour, mixing until smooth.

  6. Fold in the floured raisins and currants.

  7. Beat the eggs and incorporate them into the batter.

Bake

  1. Pour the batter into a greased cake pan and bake for about 30-40 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

Eggs
Bind the batter and add structure as the cake sets in the oven.
Baking soda
Reacts with the acidic sour milk and molasses to produce gas that helps the cake rise.
All-purpose flour
Forms the cake's main structure once its proteins set during baking.
Molasses
Adds moisture, dark colour and deep sweetness, and its acidity works with the baking soda.
Butter
Adds fat for tenderness and richness in the crumb.

The step that matters

Folding in the floured raisins and currants. Flouring the fruit helps it stay suspended rather than sinking to the bottom of the batter. Adding the fruit gently keeps the batter's air and rise intact.

Swap the currant

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

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

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