Black Cake, or Plum Cake

Ingredients

Directions

Prepare the fruit and spices

  1. Pick the currants very clean, wash them, drain them through a colander, wipe them with a towel, spread them on a large dish, set them near the fire or in the hot sun to dry, placing the dish in a slanting position.

  2. Having stoned the raisins, cut them in half, and when all are done, sprinkle them well with sifted flour to prevent sinking. When the currants are dry, sprinkle them also with flour.

  3. Pound the spice, allowing twice as much cinnamon as mace. Sift it, and mix the mace, nutmeg, cinnamon together.

  4. Mix also the liquor and rose-water in a tumbler or cup.

  5. Cut the citron into slips.

  6. Sift the flour into a broad dish.

Make the batter

  1. Sift the sugar into a deep earthen pan, cut the butter into it, warm it near the fire if too cold, stir butter and sugar to a cream.

  2. Beat the eggs as light as possible.

  3. Stir eggs into butter and sugar alternately with the flour, stirring very hard.

  4. Add gradually the spice and liquor.

  5. Stir the raisins and currants alternately into the mixture, taking care that they are well floured.

  6. Stir the whole as hard as possible for ten minutes after the ingredients are in.

Layer and bake

  1. Cover the bottom and sides of a large tin or earthen pan with sheets of white paper well buttered, and put into it some of the mixture.

  2. Spread on it some of the citron, which must not be cut too small.

  3. Next put a layer of the mixture, then a layer of citron, and so on until it is all in, having a layer of the mixture at the top.

  4. Bake the cake in a baker's oven for four or five hours, in proportion to its thickness.

  5. After baking, let it stay in the oven all night or until it gets quite cold.

  6. Ice it the next day.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Eggs
Beaten eggs trap air and bind the batter, giving the cake its structure.
Butter
Creamed with sugar, it adds richness and a tender crumb.
Flour
Provides the structure that holds the cake together once baked.
Powdered white sugar
Creamed with butter, it adds sweetness and helps give a light texture.
Raisins
Add sweetness, moisture and chewy body to the cake.
Currants
Add moisture, sweetness and chewy body throughout the cake.

The step that matters

Flouring the raisins and currants. Fruit tossed in flour is less likely to sink to the bottom of a heavy batter, so the fruit stays evenly distributed through the cake.

Swap the currant

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

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