Errr ~ The Tesco site makes it clear that they are selling the bananas by the KILO
Yes, well I missed that bit, which is why we have 6 kilos of the bastards
OK sensible suggestion which my boys love.
Push a wooden skewer into the end of each banana ~ leave the skins on. Place them in the freezer. When The Boy wants a sweet treat ~ give him a banana ice lolly. The skins will turn black but the contents, as long as the bananas are fresh, will be fine. All he has to do is peel the "lolly" and scoff it. The wooden skewers can be recycled the next time you have a surfeit of bananas
