Bones about 2.5 lbs (from 1-2 organic chicken or 1 large Grass Fed Beef marrow bone)

Carrots (2-3)

Celery (1-2 stalk)

Fresh Thyme (2-5 sprigs)

Fresh Rosemary (2-5 sprigs)

Fresh Parsley (2-5 sprigs)

Thumb size of fresh ginger sliced into coins

2 bay leaves

8-10 cups of water (you want the water to be covering everything in the pot)

1-2 tablespoons of apple cider vinegar

Salt to taste

Cook on low for several hours (8-10) or use an instant pot (120 minutes)
