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).

  2. Separate the yolks and whites of the eggs; beat the yolks well.

  3. Cream the butter and sugar together.

Make the batter

  1. Add the sour cream with the baking soda dissolved in it, then mix in the blackberry jam or mashed blackberries and spices.

  2. Gradually add the flour, then fold in the beaten egg whites until stiff.

  3. Pour the batter into a loaf pan or layer pans.

Bake and finish

  1. Bake until a toothpick inserted in the center comes out clean.

  2. If using layers, add icing flavored with lemon or vanilla between the layers.

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

What each ingredient does

Eggs
Whites beaten until stiff add lift and an airy structure to the batter.
Butter
Creamed with sugar, it traps air and adds tenderness and richness.
Flour
Provides the structure that holds the cake together as it bakes.
Baking soda
Reacts with the acidic sour cream to release gas, helping the cake rise.
Sour cream
Adds moisture and acidity, tenderizing the crumb and activating the baking soda.
Blackberry jam or fresh blackberries
Adds fruit flavor, moisture and sweetness to the batter.

The step that matters

Folding in the beaten egg whites. Stiffly beaten whites hold air that makes the cake light. Folding gently keeps that air in; stirring hard deflates the batter and yields a dense cake.
