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.

Make the batter

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

  2. Cream the sugar and butter together.

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

  4. Gently stir in the flour until just combined.

Bake and roll

  1. Pour the mixture into a well-greased 14x11 inch baking tin.

  2. Bake for 8 to 10 minutes.

  3. Turn the cake out onto sugared paper and sprinkle with castor sugar.

  4. Remove the paper from the bottom, warm the jam slightly, and spread it over the cake.

  5. Roll the cake up quickly.

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

What each ingredient does

Eggs
Trap air and set into the sponge's light, flexible structure.
Flour
Provides the protein and starch that form the cake's structure as it bakes.
Sugar
Sweetens the cake and, creamed with butter, helps trap air for a lighter crumb.
Butter
Adds fat for tenderness and flavour in the batter.
Raspberry jam
Adds sweetness, fruit flavour and moisture to the filling.

The step that matters

Roll the cake up quickly. The sponge is flexible only while warm; as it cools the starch and protein set, so it cracks if rolled late.
