Prune Cake

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°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 300°F (150°C).

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

  3. Add the prunes, sour milk, egg, baking soda, cloves, cinnamon, and nutmeg. Mix well.

  4. Gradually add the flour, stirring until just combined.

Bake and finish

  1. Pour the batter into two greased cake pans or a loaf pan.

  2. Bake for about 30-40 minutes or until a toothpick inserted in the center comes out clean.

  3. Let cool and frost with either white or chocolate icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Prunes
Add moisture and a dense, fruity sweetness to the crumb.
Sour milk or buttermilk
Adds acidity that reacts with baking soda to lift the batter.
Baking soda
Reacts with the acidic sour milk to produce gas that makes the cake rise.
Egg
Binds the batter and adds structure and richness.
All-purpose flour
Provides the structure that sets the cake as it bakes.
Butter
Adds fat for tenderness and flavor when creamed with sugar.

The step that matters

Gradually add the flour, stirring until just combined. Overmixing once flour is added develops gluten, which makes the cake tough and dense. Stirring only until the flour disappears keeps the crumb tender.

Swap the clove

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

  1. Cardamomfits better
  2. Allspicefits about as well
  3. Clovethe original
  4. Gingerfits less well

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