It's a New Year, don't forget to check the dates on all your spices, flours, etc.
My Rule - If it doesn't have a date, but I can't remember when I baught it or when I used it last... Then Its Expired by default...
And Obviously all the out-dated items go away... I know its wasteful but unfortunatly is a necessary Evil.... And actually when going through my cabinets today, I was surprised how much had expired...I now have some pretty clean cupboards though, which is a good thing. And throwing that stuff away, reminds me to be more careful this new year... Only buy what I need and when I need it.
I started by putting a piece of paper and pencil on my counter. Every time something is empty or missing, I add it to that list, so I'm not trying remember a week later and there is no possibility of getting duplicates. If its not on the list then I won't buy it. I'm on my 2nd week of this new technique, so we'll see what the rest of the year holds!
