you can of course make banana cake, or perhaps a sweet desert wine, and there is a green banana variety called plantain grown and eaten in the caribbean and in south east asia, skins are also used to make a spicy savoury dish, very nice. skins are also good as a deterrent on the way to patent offices for those wishing to tie up all creative use as with mucuna and basmati rice....
hurry we might be able to synthesize a mellow medicinal compound faster than it takes to get a treatment to market.......
or we could try drying and smoking the skins........
sorry steve, you got there first!
