The exploration of new food combinations is all well and good, but finding new applications for old pairings can be equally exciting – after all, they are old and well-used for a reason. As I expect we all know, it is eminently possible to unite chocolate and hazelnuts to devastating effect and this flapjack recipe, in my opinion, certainly does so, taking their relationship to stratospheric levels. However, be warned, no quarter is given to healthy eating here – these are full-fat and flavourful. I direct those of you looking for something a little easier on the waistline to this recipe for chewy granola bars.
