We always save pieces of vegetables (onion skins ends, carrot ends & peels, tomato pieces, celery ends, etc.) in a large Ziploc in the freezer. We also save chicken giblets, wing tips, carcasses of whole roasted birds in the freezer as well. After a few weeks, this becomes our 'Chicken Stock Kit'. We make homemade stock about once or twice a quarter. We freeze this in storage containers of various sizes, and in ice cube trays. We then use the frozen stock to flavor our dishes. If we are making gumbo, Hoppin' John, or red beans and rice, we use a couple of the large containers. If we are making a pot of green beans or some rice for dinner, we add a couple of 'chicken cubes' for flavor. Asparagus tips add a great richness to chicken stock and I always add them to our Chicken Stock Kit when we eat it.
