Good Plum Cakes

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the batter

  1. Beat the butter to a cream.

  2. Add the powdered sugar and beat until white and smooth.

  3. Separate the eggs; beat the whites to a stiff froth.

  4. Mix in the yolks and then add to the butter mixture, beating just enough to combine.

  5. Gently fold in the flour and currants without overmixing.

  6. Let the batter stand in a cold place for 2 hours.

Bake

  1. Bake in a preheated oven at 350°F (175°C) for about 1.5 hours.

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

What each ingredient does

Butter
Creamed with sugar to trap air and give the cakes a rich, tender crumb.
Eggs
Whites add lift when whipped; yolks enrich the batter and help bind it.
Flour
Provides the structure that sets the cakes as they bake.
Currants
Add pockets of fruit sweetness and chew throughout the cake.
Powdered sugar
Dissolves easily into the butter, adding sweetness and a smooth texture.

The step that matters

Folding in the flour and currants. Overmixing once flour is added develops gluten, which makes the cakes tough and dense. Folding gently keeps the batter light.

Swap the currant

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

  1. Raisinfits better
  2. Vanillafits better
  3. Figfits better
  4. Currantthe original

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