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.

Prepare

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

Make the batter

  1. Cream together the brown sugar and butter until light and fluffy.

  2. Mix in the blackberry jam, raisins, and currants.

  3. In a separate bowl, combine the sour milk and baking soda, then add to the mixture.

  4. Stir in a pinch of cinnamon and nutmeg.

  5. Gradually add the flour, mixing until just combined.

Bake

  1. Pour the batter into a greased cake pan and bake for 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

Brown sugar
Adds sweetness and moisture, and helps the cake brown and stay tender.
Butter
Adds fat for a tender crumb and rich flavor.
Blackberry jam
Adds sweetness, fruit flavor, and moisture to the batter.
Sour milk
Its acidity reacts with baking soda to help the cake rise.
Baking soda
Reacts with the acidic sour milk to produce gas that lifts the batter.
Flour
Provides structure as the batter sets in the oven.

The step that matters

Gradually add the flour, mixing until just combined. Once flour meets liquid, gluten begins to form. Overmixing toughens the cake, so stop as soon as no dry streaks remain.

Swap the currant

How well each one fits the dish's main ingredients (sugar, butter, blackberry, raisin, milk, cinnamon, nutmeg):
