Want to try using parchment paper in your baking but don't want to invest in a roll or a double roll from a big box store?

Preheat the oven to 190C/170C Fan/Gas 5 and line a 23x33cm/9x13in Swiss roll tin with baking paper. Place the eggs, sugar and vanilla seeds into a bowl and whisk until very pale, fluffy and thickened.

Grease and line the 2 Swiss roll tins with baking paper. In a large bowl, beat the egg and sugar together with an electric hand whisk for approximately 5 minutes or until light and pale.
