Cake, Plum

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

  1. Cream the butter in a bowl.

  2. Add the sugar and treacle, and mix well.

  3. Incorporate the eggs one at a time, beating well after each addition.

  4. Mix in the warm milk until combined.

  5. Gently fold in the currants, candied lemon peel, sweet almonds, and flour without overmixing.

Bake

  1. Pour the batter into a greased cake tin.

  2. Bake in a slow oven at 300°F (150°C) for at least 4 hours.

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

What each ingredient does

Butter
Creams with the sugar to trap air and give a rich, tender crumb.
Eggs
Bind the batter and add structure and richness as they set in the oven.
Flour
Provides the main structure that holds the fruit and sets the cake's crumb.
Moist sugar
Adds sweetness and moisture, and helps the cake brown during the long bake.
Currants
Supply the fruit bulk and chewy texture throughout the cake.

The step that matters

Folding in the currants, peel, almonds and flour. Overmixing once flour is added develops gluten, which toughens the crumb. Folding gently keeps the batter light and stops the heavy fruit from sinking to the bottom.

Swap the currant
