Sponge Fruit 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.

Prepare

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

  2. In a large bowl, combine the bread sponge, sugar, butter, currants, raisins, eggs, cinnamon, cloves, allspice, and baking soda.

  3. Mix well and add enough flour to achieve a stiff batter.

Bake

  1. Pour the batter into a greased baking pan.

  2. If desired, fold in walnut meats before baking.

  3. Bake immediately without waiting for the batter to rise until golden brown.

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

What each ingredient does

Bread sponge
Adds fermented flavor and some lift to the batter.
Flour
Provides structure so the stiff batter holds its shape while baking.
Eggs
Bind the batter and help set the crumb as it bakes.
Butter
Adds fat for a tender crumb and rich flavor.
Sugar
Adds sweetness and helps the crust brown.
Baking soda
Reacts with acid in the batter to release gas, helping the cake rise.

The step that matters

Bake immediately after mixing. Baking soda starts releasing gas as soon as it is moistened and mixed. Waiting lets that gas escape before the batter sets, so the cake rises less.

Swap the currant

How well each one fits the dish's main ingredients (bread, sugar, butter, raisin, egg, cinnamon, clove):

  1. Vanillafits better

  4. Currantthe original

Fit is the average pairing score against bread, sugar, butter, raisin, egg, cinnamon, clove. Candidates are from the same food group and used in at least 100 recipes.
