Label your leftovers to increase the chance they will get eaten
Since having kids we store more leftovers than ever in the refrigerator. I was getting a little overwhelmed by trying to remember how long everything had been in there. Now each time I open a jar of tomato sauce or pack a container with leftover dinner, I label it with a piece of masking tape marked with the date before putting it in the refrigerator. This has made it so much easier to know what needs to be eaten soon and what needs to be thrown out.
I'd also include the name of the item on the label -- I find that when people can see, at a glance, what's hiding in those containers, it's more likely to get eaten.
Do you have any good leftover management tips?
