Instructions
- Preheat the oven to 350 degrees Fahrenheit. Place the bones on a baking sheet or roasting pan and roast until they are well browned, about 30 minutes.
- Meanwhile, rinse all vegetables well including kombu. In a 12-quart or larger stockpot, combine combine the bones, carrots, onions, leek, celery, potatoes, yam, garlic, kale, parsley, kombu, herbs, peppercorns, spices, bay leaves, salt, and vinegar.
- Pout in the water; enough to cover the vegetables by at least 1 inch. Cover the pot with a lid and bring to a boil. Remove the lid, decrease the heat to low, and skim off the scum that has risen to the top. Simmer gently, uncovered, for 8 to 24 hours. Some of the water will evaporate; add more if the vegetables begin to peak out.
- Remove and discard the bones and large vegetable pieces, then strain the broth through a large, coarse mesh sieve or colander.
- Let cool to room temperature then refrigerate overnight.
- The next day, skim off as much fat as you can from the top of the broth, then portion into airtight containers and refrigerate or freeze.
