too many cooking apples

You could try selling them, even giving them away.

No reason why you couldn't. It's also possible to make wine from fruits other than gapes.

You'd probably have to make cider/wine then distil it. The distilation part would probably require permission from HMRC. My personal opinion is that making fuel from perfectly good food is not really a sensible idea.

Buy some weaners, faten them to porkers using surplus apples and pig pellets, (it only takes three months!), have them slaughtered and prepared for the freezer. Don't forget to save some apples for the apple sauce

(there is a DEFRA rigmarole of red tape registering but it's not too difficult)
