Blackberry 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 mixing bowl, beat the butter and sugar together until light and fluffy.

  3. Add the sour milk, beaten eggs, vanilla, cinnamon, cloves, and baking soda. Mix well.

  4. Gradually stir in the flour until just combined.

  5. Gently fold in the blackberries, being careful not to mash them.

Bake and cool

  1. Pour the batter into two greased layer cake pans.

  2. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.

  3. Let the cakes cool completely before icing.

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

What each ingredient does

Butter
Creamed with sugar to trap air, giving the cake a light, tender crumb and rich flavor.
Eggs
Add structure and richness, helping the batter set as it bakes.
All-purpose flour
Forms the gluten network that gives the cake its structure.
Baking soda
Reacts with the sour milk to produce gas that helps the cake rise.
Sour milk
Its acidity activates the baking soda and adds tenderness to the crumb.
Blackberries
Add fruit flavor and moisture to the batter.

The step that matters

Folding in the blackberries. Cooked blackberries are soft and can break down easily; folding gently keeps them in pieces and avoids streaking the batter purple. Overmixing after the flour is added also toughens the cake, so stir only until combined.

Swap the clove

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

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

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