Ingredients

  • 4 pounds meaty beef bones (such as shank or neckbones)
  • 1 calfs foot, cleaned and split (see Note)
  • 1/3 cup vegetable oil
  • 4 cups finely chopped yellow onions
  • 2 leeks, white part only, well rinsed and sliced
  • 3 cups chopped peeled carrots
  • 2 small or 1 medium parsnip, peeled and chopped
  • 1 1/2 tablespoons dried thyme
  • 4 bay leaves
  • 6 whole cloves
  • 12 black peppercorns
  • 6 parsley sprigs
  • 1 tablespoon salt
  • 1 can (6 ounces) tomato paste
  • Water, as needed

Method

  • Preheat the oven to 400F.
  • Spread the beef bones and calfs foot in a baking pan just large enough to hold the meat in a single layer.
  • Bake until the meats are very brown, 1 1/2 hours.
  • Turn the pieces occasionally and drain the rendered fat as necessary.
  • Heat the oil in a large pot.
  • Add the onions, leeks, carrots, and parsnips and cook over high heat, stirring often, until well browned, about 25 minutes.
  • Add the browned bones and calfs foot to the vegetables, along with the remaining ingredients.
  • Pour 1 cup water into the pan in which the meats were browned and set over high heat.
  • Stir and scrape up any caramelized particles from the bottom and sides.
  • Pour the liquid into the pot.
  • Add additional water to cover the ingredients by 2 inches, and set the pot over medium heat.
  • When the stock reaches a boil, skim, reduce the heat so the liquid simmers, partially cover, and simmer for 4 hours.
  • Skim occasionally.
  • Strain out and discard the solids.
  • Refrigerate the stock, or chill and then freeze.
  • Before using the refrigerated stock or freezing chilled stock, remove any fat that has solidified on top.
