Fruit 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 together the brown sugar and butter.

  2. Add the flour, raisins, currants, citron, cloves, mace, sour cream, baking soda, and dark jelly. Mix well.

  3. Dredge the fruit with a little flour to prevent sinking.

  4. Pour the batter into a greased cake pan.

Bake

  1. Bake for 3 hours or until a toothpick inserted in the center comes out clean.

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 give the cake richness and a tender crumb.
Brown sugar
Adds sweetness and moisture, and helps the cake brown and stay soft.
Flour
Provides the structure that holds the batter and fruit together as it bakes.
Sour cream
Adds moisture and acidity, which helps the baking soda react and the crumb stay tender.
Baking soda
Reacts with the sour cream's acidity to produce gas that helps the cake rise.
Raisins
Add chewy sweetness and moisture throughout the cake.

The step that matters

Dredging the fruit with flour. Heavy dried fruit sinks to the bottom of a batter during baking. Tossing it in a little flour helps the pieces grip the batter and stay suspended as the cake sets.

Swap the mace

How well each one fits the dish's main ingredients (sugar, butter, flour, raisin, currant, clove, cream):

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Allspicefits better
  4. Macethe original

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