Yield: 2 quarts brown veal stock
1. Combine the cooked bones and water in a pot and bring to a simmer. Reduce the heat so that the water stays just below a simmer, about 180 F; or place, uncovered, in an oven preheated to between 190 F and 200 F, and cook for about 10 hours. Add the remaining ingredients, bring the water temperature back up to just below simmering and cook for one more hour. Strain out the bones and vegetables, and pass the stock through a kitchen cloth or cheese cloth.
2. This stock can be used as is as a braising liquid (lamb shank! short ribs!) or to enrich stews and legumes and soups. Or it can be reduced to one quart and used as a sauce base (i.e. added to sautÃ©ed mushrooms and shallots, added to shallots, wine and mustard, etc.)
For White Veal Stock:
1. Combine the bones and the water in a large pot and bring the water up to a full boil over high heat. Strain the bones then rinse them well under cold water.
For Brown Veal Stock:
1. Preheat the oven to 450 F. Lightly oil a roasting pan or sheet tray large enough to contain the bones without crowding them. Roast in the oven, turning occasionally, until they are appealingly browned and smell delicious. They'll lose about a third of their weight and the stock will be especially flavorful.
