Blueberry 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

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

  2. In a large bowl, mix the sour milk, blueberries, sugar, baking soda, and eggs.

  3. Gradually add flour until the batter is thick.

Bake

  1. Pour the batter into a greased baking pan.

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

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

What each ingredient does

Flour
Provides the structure that holds the thick batter together as it bakes.
Eggs
Bind the batter and help set the crumb during baking.
Sour milk
Adds moisture and acid that reacts with the baking soda.
Baking soda
Reacts with the acidic sour milk to produce gas that lifts the cake.
Sugar
Sweetens the cake and helps it brown while baking.
Blueberries
Add moisture, tartness and flavor throughout the cake.

The step that matters

Gradually add flour until the batter is thick. Stirring flour into a batter develops gluten, so mixing too much makes the cake tough. Add flour gradually and stop once the batter is thick and just combined.
