Alexandria 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 cake batter

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

  2. 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, cinnamon, nutmeg, and baking soda dissolved in sour cream.

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

Bake and ice

  1. Divide the batter into three layers and bake for 25-30 minutes.

  2. For the icing, boil 1 cup of sugar with 4 tablespoons of water until it reaches a soft ball stage.

  3. Beat the egg white until stiff, then gradually add the hot syrup while continuing to beat.

  4. Add vanilla to taste and spread the icing between the layers and on top of the cake.

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

What each ingredient does

Eggs
Bind the batter and add structure and richness as the cake sets.
Butter
Creamed with sugar, it traps air and gives the cake a tender crumb and fat-based richness.
Baking soda
Reacts with the acidic sour cream to release gas, helping the cake rise.
Blackberry jam
Adds sweetness, fruit flavor and moisture to the batter.
Flour
Forms the cake's structure once mixed in and baked.
Sugar
Sweetens the cake and, creamed with butter, helps create a light texture.

The step that matters

Beat the egg white while adding the hot syrup. The syrup must be hot enough to cook the egg white as it is beaten in slowly; adding it too fast or cold can leave the icing runny or grainy and unstable.

Swap the blackberry
