Blimey I came on to post something I thought might be helpful to people about how to keep fruit from going off but this conversation seems to have gone off on a tangent somewhat and I don't know that I dare!
Sod it, I will anyway in the hope it might be useful to someone.
Has anyone used a food dehydrator. I bought one a couple of months ago for about £30 and it is fab and very cheap to run. I currently have four pineapples, all short dated and massively reduced in Tesco, chopped and dehydrating. The dehydrated fruit can then be eaten on its own as a snack, used with cereal etc or rehydrated and used in the normal way at a later stage. And it will last for months and months in a jar. I regularly do strawberries and raspberries, apples, bananas (grapes and blueberries aren't worth the effort since they take too long). Veg works too. All can be bought when on offer, dehydrated and kept for months (or years in some cases).
I appreciate this is one of those things where you have to spend a little to save and its also clearly not aimed at people who are in a situation where they are visiting food banks etc, more at those of us who want to take advantage of multi buy offers on fruit and veg.
