The nation’s favourite baking show draws to a close tonight. Each week we’ve watched with rumbling tummies and gaping mouths as the Great British Bake Off contestants create delectable goodies containing enough fat and sugar to supply Willy Wonka for a year. If, like us, you want to enjoy the final tonight with a plate of something sweet and delicious but prefer not to exceed your Healthy Food Guide boundaries (which are working very nicely, thank you), be your own star baker and whip up a batch of GBBO 2012 winner John Whaite’s pistachio and rosemary biscotti.
