This is a cooking item that is good to have at all times. Making a large pot once a month ensures having it on hand.
In a large pot, cover bones with water by about an inch. Bring just to a boil. Skim top of boil after about 5 minutes. Add remaining ingredients, add more water so everything is covered by at least 2 inches. Bring to a simmer, cover and simmer for 6-7 hours, skimming occasionally.
Remove from heat and let cool. Strain through a fine strainer. Discard solids. Place stock in refrigerator, allowing fat to rise to the top. Skim fat off, then store in freezer for later use in 2-4 plastic containers.
