Sponge Cake Roll

Oven, in the book's wordsA quick oven

Ingredients

Directions

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

Prepare

  1. Preheat the oven to 400°F (200°C).

  2. Sift the baking powder into the flour and add the sugar.

  3. Break the eggs into the mixture (do not beat separately) and beat everything together well.

Bake and roll

  1. Pour the batter into square jelly tins and bake until done.

  2. Once baked, turn the cake out onto a molding board.

  3. Spread currant jelly over the cake, roll it up, and wrap each roll in a clean cloth until cool.

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

What each ingredient does

Eggs
Provide structure and lift, setting the sponge as they cook.
Flour
Forms the main structure that holds the cake's crumb together.
Sugar
Adds sweetness and helps keep the sponge tender and moist.
Baking powder
Releases gas during baking so the sponge rises and becomes light.
Currant jelly
Adds sweetness, moisture and a fruity flavour inside the rolled cake.

The step that matters

Beating everything together well. Eggs trapped in the batter with air are what lift a sponge. Thorough beating incorporates air evenly so the cake rises light, while under-beating leaves a dense, uneven crumb.

Swap the currant

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

  2. Vanillafits better
  3. Lemonfits better
  4. Currantthe original

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