Ingredients

Directions

The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the batter

  1. Cream the butter in a large bowl.

  2. Add the sifted sugar and flour, mixing well.

  3. Beat the eggs in a separate bowl and add them to the mixture.

  4. Stir in the currants and mix everything together for 30 minutes.

Bake

  1. Pour the batter into a buttered tin.

  2. Bake in a hot oven at 400°F (200°C) until done.

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 cake a rich, tender crumb.
Sugar
Sweetens the cake and, creamed with butter, helps give a soft texture.
Flour
Provides the main structure that holds the cake together as it bakes.
Eggs
Add structure and moisture, and help bind the batter and lift the crumb.
Currants
Add fruity sweetness and chewy bits throughout the cake.

The step that matters

Stir in the currants and mix everything together for 30 minutes. Once flour is in the batter, long mixing develops gluten, which can make the cake tough and dense. Stir gently and only until the currants and flour are evenly combined.

Swap the currant

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

  4. Currantthe original

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