Plain Soda Cake

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.

Prepare

  1. Preheat the oven to 350°F (175°C).

Make the batter

  1. In a large bowl, cream together the butter and sugar until light and fluffy.

  2. Gradually add the flour, carbonate of soda, and milk, mixing until smooth.

  3. Fold in the currants or sultanas and candied peel.

Bake

  1. Pour the batter into a greased cake tin.

  2. Bake for about 2 hours, or until a skewer inserted into the centre comes out clean.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Flour
Forms the structure that holds the cake's crumb together as it bakes.
Butter
Adds richness and a tender texture, and traps air when creamed with sugar.
Sugar
Adds sweetness and, when creamed with butter, helps create a light texture.
Carbonate of soda
Reacts in the batter to produce gas that helps the cake rise.
Milk
Adds moisture and loosens the batter to a smooth consistency.
Currants or sultanas
Add sweetness and chewy pockets of dried fruit throughout the cake.

The step that matters

Creaming the butter and sugar until light and fluffy. Beating fat and sugar together traps tiny air bubbles that expand in the oven and help the cake rise and stay tender. Under-creamed butter leaves a dense, heavy cake.

Swap the currant

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

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

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