Hate to be wasteful of food, but hate the idea of making myself sick by cooking something I blew the dust off of even more ... now the cupboard is down to stuff that is packaged in a way that means deterioration is measured in fairly lengthy spans of time (tins, soup & sauce packets, etc.) and/or things that I know have been purchased within living memory (I know I keep buying a new suppy of barley 'cause that's my indispensable side dish/salad food). Even unearthed a mini-shelf in the rear corner that I'd forgotten I owned, so now that's up front and being a useful organizer for current stuff. And now I have a supply of storage jars to fill up with new stuff (after washing and airing)
This keeps up, I may even vacuum!
