After muddling through with three small drawers in a fridge freezer, I today have a big upright freezer just waiting for stuff. I'd love to do a lot more bulk buy and freezing, and batch cooking, and saving leftovers, but my tupperware is a bit more local takeaway than Lakeland - what should I treat myself to for freezer storage? (That sounds v sad, but hey, it's Housekeeping, you understand...)
