Salad Dressings

Every couple of months I give more than a glance to the door shelves in the refrigerator.  Usually, we just glance and grab the ketchup or mayonnaise.  Looking more carefully, I realize that some of the salad dressing have been with us for a v-e-r-y long time.  Not a good thing.  Today I cleaned out old dressings and will try to date them when I purchase new bottles; then I can really know how old they are and keep them rotating.
