The humble Swiss Roll got a bit of a make over on last night's Great British Bake Off

Perfecting the Swiss Roll swirl is essentially rocket science

Resident hipster Iain (fifth from the right in the shot above) had a very clever method of mastering the Swiss Roll in the Signature Bake challenge - cutting slits into his sponge to make rolling it up a lot easier. Paul and Mary were having none of it, and sadly for Iain, he wasn't proved right as his Swiss Roll split. We're pretty sure if he wasn't so Northern Irish and beardily charming, it would have been the end of his baking career right there.

New aprons change everything

Moving the show from BBC Two to BBC One is apparently something of an upgrade, and the bakers were treated to new grey aprons after four years in white ones. This doesn't seem to mean that the contestants are allowed to change their clothes during the show, however. The filming takes place over two days, but it has been well documented that the contestants have to come back for the second day in the same clothes they were in previously for continuity. Hopefully they're treated to a laundry session overnight....
