Blackberry Jam 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.

Make the batter

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

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

  3. Add the eggs one at a time, mixing well after each addition.

  4. Stir in the blackberry jam and sour milk.

  5. In a separate bowl, combine the flour, baking soda, nutmeg, allspice, and cinnamon.

  6. Gradually add the dry ingredients to the wet mixture, mixing until just combined.

Bake and cool

  1. Divide the batter into prepared cake pans and bake for 25-30 minutes or until a toothpick comes out clean.

  2. Let the cakes cool before frosting.

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

What each ingredient does

Butter
Creams with the sugar to trap air, giving a light, tender crumb and rich flavor.
Eggs
Add structure and richness, helping the cake set and hold its rise.
Flour
Forms the structure of the cake as its proteins set during baking.
Baking soda
Reacts with the sour milk to produce gas that lifts the batter.
Blackberry jam
Adds fruit flavor, sweetness, and moisture to the crumb.
Sour milk
Its acidity activates the baking soda and tenderizes the crumb.

The step that matters

Mixing the dry ingredients into the wet mixture. Overmixing once flour is added develops gluten, which makes the cake tough and dense. Mix only until just combined so the crumb stays tender.
