I did the same, bought a freezer for the garage and I defrosted it in spring, but now it is packed full of soups (courgette and squash), gooseberries, redcurrants, plums, beans, mange tout and I am finding it hard because I have so much more still to put in for the winter.
My favourite thing is to pick blackberries... just doing that these last few days... to make jam mostly but I like to keep the big ones, shake them in sugar (it separates them nicely) and freeze for winter... absolutely lovely to take out at Xmas and have with yoghurt or custard, or even on their own, like little iced, sweet fruits... yum, mouth's watering now!
