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 the batter

  1. Preheat oven to 300°F (150°C).

  2. In a large bowl, cream together butter and brown sugar.

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

  4. Stir in molasses and melted currant jelly mixed with hot water.

  5. In another bowl, combine browned flour, baking soda, spices, and dried fruits.

  6. Gradually add dry ingredients to wet mixture, stirring until well combined.

Bake

  1. Pour batter into a greased cake pan.

  2. Bake for several hours 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

Eggs
Bind the batter and add structure as they set in the oven.
Butter
Adds richness and tenderness by coating flour and sugar when creamed.
Brown sugar
Adds sweetness and moisture, and helps the cake brown.
Flour
Forms the structure of the cake as the batter sets.
Baking soda
Reacts with the molasses acidity to lighten the batter.
Molasses
Adds dark color, moisture, and a deep sweet flavor.

The step that matters

Gradually add dry ingredients to wet mixture. Adding the dry ingredients in portions and stirring just until combined keeps the batter smooth and helps prevent lumps and overmixing, which can make the cake tough.

Swap the mace

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

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

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