While browsing the latest issue of Parents Magazine I saw a tip for labeling food containers. It suggested using a dry erase maker. It works wonderful and wipes right off.
I hate to admit this but there was quite a bit of food waste before I started doing this. I would have to guess low long that half can of peaches had been in the refrigerator. When I wasn't sure I played it better safe then sorry and tossed the items. No more guessing and when I clean out the frig on Thursday's I know exactly what items need tossed. It certainly works for me!
