Every fridge in almost every communal kitchen in any backpacker hostel in the world, in the Southern Hemisphere in particular, has at least one avocado in it. Cut in half, the avo is left there to brown and to finally become inedible. Well, that avos cut in half don't necessarily have to brown, shows this short video... quite a handy advice, isn't?
If you got any good (budget) backpacker recipes, share them with Hostelbookers and get featured in their Backpackers Recipe Guide! For more info about Hostelbookers' "#HostelKitchen Approved" competition, check their blog! Good luck!
