NOTE 1 Remove the lining and trim off a bit of the stiff edges, which would cause it to crack during rolling. NOTE 2 Use the baking / parchment paper dusted with castor sugar to help you roll the cake up, while it is still hot, If the cake cools down, it will crack when you roll it up. NOTE 3 Leave the rolled cake to cool completely in the parchment paper. I usually cover the parchment rolled swiss roll with a clean damp tea towel. I find that this keeps the sponge soft during the cooling process and makes it easier to re-roll it after it has cooled.
