Peeling green bananas: It is helpful to cut off each end of the banana, then score the skin length-wise. Basically you want to cut through all the skin on at least once side but try not to damage the white flesh of the banana itself. It should be easy to peel off the skin afterwards. You can oil your hands to prevent too much sap from the bananas sticking to them. It can stain, so try to avoid getting it on your clothes.
