Harrison Cake

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Preheat the oven to 300°F (150°C).

Make the batter

  1. In a large bowl, cream the butter and molasses together.

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

  3. Stir in the flour, baking soda, and spices until combined.

  4. Fold in the raisins.

  5. Pour the batter into deep pans.

Bake

  1. Bake for 3 hours 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 cake together as it bakes.
Molasses
Adds sweetness, moisture, and a dark color to the batter.
Butter
Adds richness and tenderness through fat creamed into the batter.
Eggs
Bind the batter and add structure and moisture as they set.
Baking soda
Reacts with the acidity in the batter to help it rise.
Raisins
Add chewy texture and concentrated sweetness throughout the cake.

The step that matters

Bake until a toothpick comes out clean. A long bake at low heat sets the batter gradually. Pulling it early leaves the centre wet and gummy, while over-baking dries the cake out.
