In the third episode of the Great Comic Relief Bake Off, Jo Brand welcomes four more celebrities into the tent to lay bare their baking skills. They are David Mitchell, Michael Sheen, Radio 1 DJ Jameela Jamil and Sarah Brown. The nervous bakers get off to a crumbly start in the signature challenge (24 portions of shortbread), face one of Paul's notoriously difficult recipes in the technical challenge (six mini pork pies) and put their unique stamps on the showstopper bake (triple-tiered pavlova with fruit). Tensions are high and confusion is rife, but who will impress and who will miss the mark? Judged by legendary cookery writer Mary Berry and acclaimed master baker Paul Hollywood, these four will have to pull out all the stops to impress the judges and be crowned Comic Relief Star Baker. Comedian Ed Byrne visits a Comic Relief-funded project in Uganda, showing how the money raised on Red Nose Day really does help change people's lives. (thetvdb.com)
