We still have a few mystery packages in the freezer, but we have gotten much better at labeling, although that doesn't always work either. Last week, I had found a package of red stuff that had frozen in such a way that I could see sauce, but that's it. I figured it was our basic sauce that we make a large batch of and then doctor to suit for each dish, so I pulled it out to make pasta alla vodka. Nope, it was sub sauce, but it worked!
We're also bad at buying stuff on sale or impulse buying if we see something special, like the silkie chicken I bought a while back, and forgetting about it until we go freezer diving. I ran across the chicken last week, but already had a couple of chicken meals, but it's going on the menu in some form for the coming week.
