Firstly you flip the (cool, empty) pan over and identify the 'indent' thingy that holds the handle in place:
It's not the hardest thing I've made, clearly, but it does mean the pan and cooking gubbings will fit much more easily in my frame bag now. I'm just waiting on the Alpkit MyTiMug (Spoiler alert - Mum and Dad have got me it for christmas...) and I can get going on my "posh bivvy brunch/great bivvy bake off" recipe book..
