Tar Heel 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. Cream together the butter and pulverized sugar until light and fluffy.

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

  3. Gradually stir in the flour, then fold in the raisins, currants, citron, orange peel, and chopped almonds.

  4. Mix in the brandy and allspice until well combined.

Bake

  1. Pour the batter into a greased cake pan and bake for several hours 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

Butter
Creams with sugar to trap air, giving the cake a light, tender crumb and rich flavor.
Eggs
Add structure and richness, binding the batter as the cake bakes and sets.
Flour
Provides the structure that holds the dense batter and fruit together as it sets.
Raisins
Add moisture and chewy sweetness throughout the cake.
Currants
Add moisture and concentrated tart-sweet fruit flavor throughout the cake.
Brandy
Adds aroma and flavor, and its alcohol helps keep the cake moist.

The step that matters

Baking until a toothpick comes out clean. A cake this dense with fruit can look set outside while the center is still wet. Testing the center with a toothpick confirms the batter has fully set before cooling.

Swap the currant

How well each one fits the dish's main ingredients (sugar, butter, egg, flour, raisin, orange, almond):

  1. Vanillafits better
