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.

Prepare

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

Make the batter

  1. In a bowl, cream together the sugar and butter.

  2. Add the eggs and mix well.

  3. Dissolve the baking soda in the buttermilk and add to the mixture.

  4. Gradually add the flour, blackberry jam, cloves, cinnamon, and nutmeg. Mix until well combined.

Bake and assemble

  1. Pour the batter into prepared cake pans and bake until a toothpick comes out clean.

  2. Let cool and use chocolate filling between layers.

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

What each ingredient does

Butter
Creams with sugar to trap air and add richness and tender texture.
Eggs
Bind the batter and add structure and moisture as the cake sets.
Baking soda
Reacts with the acidic buttermilk to produce gas that helps the cake rise.
Buttermilk
Adds acidity that activates the baking soda and tenderizes the crumb.
Flour
Provides the structure that holds the cake together as it bakes.
Blackberry jam
Adds sweetness, fruit flavor and moisture to the batter.

The step that matters

Dissolve the baking soda in the buttermilk. Baking soda needs an acid to react and produce gas; dissolving it fully in the buttermilk spreads the reaction evenly so the cake rises uniformly without pockets or a bitter, soapy taste.

Swap the clove

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

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

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