Next time you have a roast chicken for dinner, be sure to save the leftover carcass, bones and scraps to make chicken stock.
It is way tastier than the stock you buy in the store, and super easy to make in a slow cooker.
Here are some pictures of the process.

Be sure to fill the slow cooker up with lots of roast chicken scraps and vegetables for a more flavorful stock.

Stock after 12 hours.

Clear stock left after pulling cheesecloth, no need to strain.
