Swiss Roll

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

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

  2. Sift the flour and baking powder together.

Make and bake the sponge

  1. Whisk the eggs and sugar until creamy.

  2. Gently fold in the flour mixture, adding a little milk if necessary.

  3. Pour the batter into a greased baking tin and bake for 8 to 10 minutes.

Roll

  1. Turn the cake out upside down onto sugared paper.

  2. Spread the warm jam on top and roll the cake up tightly.

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

What each ingredient does

Eggs
Whisked with sugar to trap air, giving the sponge its light structure.
All-purpose flour
Forms the gluten network that sets the sponge's crumb once baked.
Baking powder
Releases gas in the batter, helping the sponge rise in the oven.
Castor sugar
Helps whisk air into the eggs and adds sweetness and tender texture.
Warm jam
Adds sweetness and fruit flavour, and its warmth keeps the sponge pliable for rolling.

The step that matters

Rolling the warm cake. The sponge must be rolled while still warm and pliable, because cooled cake loses flexibility and cracks. Rolling it tightly right after the jam is spread keeps the spiral even.
