Black 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 the oven to 300°F (150°C).

  2. Cream the butter and brown sugar together until light and fluffy.

  3. Add the sweet milk and molasses, mixing well.

  4. In a separate bowl, beat the egg whites until stiff peaks form and set aside.

  5. In another bowl, combine the egg yolks with the browned flour, cream of tartar, baking soda, mace or nutmeg, cinnamon, and cloves.

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

  7. Fold in the currants, citron, and raisins.

  8. Gently fold in the beaten egg whites until just combined.

Bake

  1. Pour the batter into a greased cake pan and bake for 3 hours.

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

What each ingredient does

Eggs
Egg whites whipped to stiff peaks lighten the batter, and yolks add richness and binding.
Browned flour
Provides the structure of the cake and a deep, toasty flavor and dark color.
Butter
Creamed with sugar to trap air and add tenderness and richness to the crumb.
Brown sugar
Creamed with butter for a moist texture and molasses-like sweetness and color.
Baking soda
Reacts with the acidity of cream of tartar and other ingredients to help the cake rise.
Currants
Add chewy texture and concentrated fruity sweetness throughout the cake.

The step that matters

Gently fold in the beaten egg whites. Egg whites hold air from whipping, which gives lift. Folding gently, only until combined, keeps that air from deflating and keeps the crumb light.

Swap the mace

How well each one fits the dish's main ingredients (butter, sugar, milk, molasses, egg, flour, cream):

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

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