That's a great idea to use the left over carcus that way...also noticed most stores...but for sure at Coto's you often times can find chicken carcuses for very cheap and that way you could just make a large pot of stock and feeze it for using later....to add flavor I always put in onion, garlic, celery, carrots, bay leaf, peppercorns, fresh parlsey....and simmer for a few hours or put it in my large pressure cooker which cuts the time down.
