mine have already started to get some condensation on them and there's LOADS of them to use up!! i'll move them into the cupboard but i think that might make them sprout now. It'd be really good if i could pre-cut them into chips though.
Yes, you can freeze them. I would par-boil them, not too much, then spread them out on trays and open-freeze them. Then portion them up and put them into freezer bags. That way they won't all freeze in one big lump!
If you take them out of the plastic bag and store them in the dark in paper or a pillowcase or something in which they can 'breathe' they will be fine. It's only the plastic that causes the condensation. I never, EVER keep vegetables of any sort in the plastic they come in. Potatoes will last weeks/months in a dry, dark place.
You could stick them all in the oven in foil and bake them then freeze them whole and take em out as you need them that way you can cut off the skins and reheat and use em for mash, or use for roasties, chips baked potatos or potato skins.
