Plum 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 your oven to 300°F (150°C).

  2. Collect all your ingredients together.

Make the batter

  1. Work the butter to a cream, then beat in the sugar.

  2. Whisk the eggs for 30 minutes, then add them to the butter and sugar mixture.

  3. Add the flour and spices, then beat all together for 1.5 hours.

  4. Mix in the brandy and candied peel.

Bake

  1. Pour the mixture into a buttered cake tin.

  2. Bake for 2.5 hours.

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

Flour
Provides the structure that holds the cake together as it sets.
Butter
Adds fat and richness, and creamed with sugar it traps air for a tender crumb.
Eggs
Add structure and set the crumb, and the whites add lift through trapped air.
Sugar
Sweetens the cake and helps the butter hold air when creamed.
Currants
Add chewy sweetness and fruity flavour throughout the cake.
Raisins
Add chewy sweetness and moisture throughout the cake.

The step that matters

Beating the batter for 1.5 hours. Long beating incorporates air and develops the batter's structure, but overmixing after the flour is added can toughen the crumb, so keep the beating steady and even.

Swap the currant

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

  1. Vanillafits better
  2. Figfits better

  4. Currantthe original

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