Food expiration can come with some surprisingly tricky time guidelines. While packaged food often comes with a stamped date to follow, I frequently discover the dates have disappeared and can only decipher a couple of digits. Take the guessing game out of the picture (and avoid getting sick from food that's unsafe to eat) by getting in the habit of labeling your food.
Keep your labels and marker in a kitchen drawer so they're handy whenever you're storing leftovers in the refrigerator or freezing ingredients for future use. You'll end up wasting less (and saving money) when you don't have to question which month you made that grilled chicken and decide to chuck it just in case. Happy labeling!
