Beef Stock

Directions

1. 1
   Preheat the oven to 400° F.

   Add the beef bones to a 8-10 quart dutch oven.
3. 3
   Lay the beef bones on a rimmed baking sheet or roasting pan.
4. 4
   Chill the beef stock for several hours or overnight, then use a spoon to remove any congealed fat on top. Discard the fat.
5. 5
   Drizzle 1 teaspoon of olive oil over the bones and sprinkle with 1 teaspoon kosher salt. Toss the bones and spread into an even layer in the Dutch oven. Roast for 40-45 minutes.

   Drizzle 1 teaspoon of olive oil over the bones and sprinkle with 1 teaspoon kosher salt. Toss the bones to coat and spread into an even layer. Roast for 40-45 minutes.
7. 7
   Transfer the beef stock to a glass storage container with a tight fitting lid or plastic storage container. Refrigerate for up to a week or freeze the beef stock for up to 3 months. (note: I recommend freezing stock in a plastic container, because the liquid will expand as it freezes and you don't want it to break the glass if overfilled.
8. 8
   Toss the celery, onions and carrots with the remaining 1 teaspoon of olive oil and the remaining 1/2 teaspoon kosher salt.

16. 16
    Skim most of the grease from the dutch oven, leaving about 1 tablespoon.
17. 17
    Place the sheet pan over a burner on the stove over medium high heat and add the tomato paste. Use a pot holder or protective silicone mitt to hold the edge of the pan while stirring and cooking the tomato paste until it darkens and you can smell the aromas.

    Place the pot or pan on the stovetop over medium high heat and add the tomato paste. Cook, stirring constantly until the tomato paste starts to take on more color and darken.

    Depending on how high the sides of your pan are, add half cup to one cup of water and cook, scraping up the browned bits of fond from the bottom of the pan. Do this until most of the fond is loosened from the pan.
