I have a habit of re-using things, especially in my kitchen. I hate to only use a jar or container one time and then throw it away. I keep the plastic jars A.'s instant coffee comes in, the empty containers of cottage cheese and sour cream, any glass jars, ziploc bags if I can easily wash them (so not if they've had anything really greasy or raw meat in them), and of course, canning jars and lids get used over and over again.
Most of these things end up in my freezer at some point, and I always label things I put in my freezer, on the lid with a permanent marker. Most of my food containers have been labeled more than once. Sometimes so many times I run out of space on the lids or on the bags.
It's kind of funny to track what's been in the containers with that particular lid.
What this means is that you can never trust the lid that's on a container to actually tell you what's in that container. That canning jar lid, for instance, is currently on a jar containing pickled radishes and onions. It's not sauerruben.
Likewise, sour cream or cottage cheese containers are just as likely to have leftover baked beans or tomato sauce in them as the dairy products suggested by their labels.
This is why when my sister visits, she always holds up whatever she's taken out of the refrigerator and asks what's really in it. Because it really could be anything, and only I can tell for sure.
So tell me: Do you do this? Or do all your containers tell the truth about their contents?
