It might sound like a daft one but here goes...
As a kid we used to have a “tata man” who delivered giant child-sized bags of potatoes that would last 2-3 months. I got a small bag the other week and left them in a dark cupboard and they barely lasted a fortnight.
How do you store yours? I know that places rurally store potatoes for 6 months at a time in potato stores (or so I’m led to believe from fiction books) but how can I recreate that in surburbia??
