Mary Berry chocolate cups using balloons on The Great British Bake Off 2014 Masterclass

Mary Berry shows how to make chocolate cups using balloons as the mould on The Great British Bake Off 2014 Masterclass.

Mary dips the balloons filed with air in a bowl of melted chocolate several times to get a leaf shape. She then placed them in the fridge to set. Once set they removed from the fridge and the air removed from the balloons inserting a small pin.

Once the air has escaped, the balloon will fall away from the chocolate, leaving a mould.
