Instructions
Preheat oven to 350f.
Wash and dry the raw bones. Place the bones on a roasting pan and toss them with a few spoonfuls of tomato paste and flour. Chop vegetables into rough chunks and place on separate pan.
Roast both pans until everything is browned – watch out for black spots, avoid by turning the bones and vegetables.
Dump bones and vegetables into a large pot and fill with cold water. Add the thyme, peppercorns and bay leaves.
Simmer gently until reduced to desired concentration, perhaps 7 hours for beef or veal, 5 hours for chicken. Stir gently during cooking and skim off any scum or oil that appears.
Lift out the bones and vegetables, pour through colander (to remove large solids) into another container, then pour through a fine strainer, and finally cheesecloth as many times as possible to remove all solid particles from the stock.
