Step 1

Place bones in crock-pot.

Step 2

Add vinegar, salt, pepper and any onions, carrots and celery that you want (as well as any other seasonings you feel like throwing in).

Step 3

Cover with water and put the lid on the crockpot.

Step 4

Turn it on to low and allow the bones to cook at least 8 hrs.**  (Cooking it longer will not hurt anything—you’ll just get more nutrients from the bones.)

Step 5

Strain out the bones, skin and vegetables.***

Step 6

Use broth immediately or once cooled, divide into containers and freeze.****
