Neapolitan Cake

Ingredients

Directions

Make the dark cake

  1. Make the dark cake: combine butter, two cups of brown sugar, one cup of molasses, one cup of strong coffee, four and a half cups of flour, four eggs, two teaspoons of soda, two teaspoons of cinnamon, one teaspoon of cloves, one teaspoon of mace, one pound of raisins, one pound of currants, and a quarter pound of citron; bake in round pans with straight sides until the loaves are one and a half inches thick.

Make the white cake

  1. Make the white cake: combine one cup of butter, four cups of powdered white sugar, two cups of sweet milk, two cups of corn starch mixed with the flour, four and a half cups of sifted flour, the whites of eight eggs, and six teaspoons of baking powder; flavor slightly with bitter almonds; bake in the same pans as the dark cake to achieve the same thickness.

Assemble and frost

  1. After the cakes are cooled, spread a thick lemon frosting on each black loaf: whisk the white of one egg lightly, grate the rind of two lemons, add the juice of three lemons, and mix with powdered sugar until a thick frosting forms; lay the white and black loaves alternately and frost all over, using only lemon flavoring.

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

What each ingredient does

Brown sugar
Adds sweetness and moisture and deepens the colour of the dark loaves.
Molasses
Adds dark colour, moisture and a rich, slightly bitter flavour to the dark cake.
Eggs
Provide structure as they set, binding the batter into a firm crumb.
Baking powder
Releases gas in the batter, helping the white cake rise and become light.
Butter
Adds fat for tenderness and richness in both cakes.
Raisins
Add chewy texture and natural sweetness to the dark cake.

The step that matters

Baking the loaves to the same thickness. The dark and white loaves must be baked in the same pans to the same thickness so they stack evenly; uneven loaves bake unevenly and make the alternating layers sit unevenly.

Swap the mace

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

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

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