Bone Broths

bones, cartilage, skin, etc. (chicken, beef, turkey, etc.)
enough water to cover bones
¼-1/2 cup apple cider vinegar
1 onion (optional)
a few carrots (optional)
a few celery sticks (optional)
1 teaspoon pepper or crushed peppercorns (optional)

Add all ingredients to crockpot and cook on low for 48-72 hours. Continue to add water as needed to maintain bone coverage while cooking. Strain and refrigerate or freeze. Enjoy!

(Meat broths, made from meat, bones, etc., are simmered on the stovetop from 1-3 hours and are also beneficial. Do not add apple cider vinegar for meat broths.)
