step 1
Put the leftover bones and skin from a chicken carcass into a large stock pot and cover with cold water. Add veggies like celery, onion and carrots. Add salt and pepper.
step 2
Bring to a boil and immediately reduce heat to bring the stock to barely a simmer. Simmer uncovered at least 4 hours to 5 hours.
step 3
Remove the bones and strain the stock.
step 4
If making stock for future use in soup you may want to reduce the stock by simmering a few hours longer to make it more concentrated and easier to store.
