Ingredients

• 1kg of mixed organic beef bones short ribs, oxtails, knuckles, and neck bones
• 1 tablespoon olive oil
• 2 medium organic carrots
• 3 organic celery stalks
• 2 medium organic onions
• 2 tablespoons organic apple cider vinegar
• 1 organic bay leaf
• 4 sprigs of organic parsley

Method

1. Prepare the bones: Heat the oven to 400 degrees. Place the bones on a baking tray and drizzle with olive oil.
2. Roast the bones: Place the tray in the oven, roasting for 30 minutes. Turn the bones, then roast for another 30 minutes.
3. Prepare the vegetables: Chop the carrots, celery, and onions roughly. You'll discard these later, so you don't need to be precise
4. Combine stock ingredients: Place the roasted bones, chopped vegetables, bay leaf, and cider vinegar in a large stock pot or crock pot. Cover with water so that the ingredients are under at least 2 inches of liquid. At this point, you can also add in any other flavoring ingredients that you want in the broth.
5. To cook the broth on the stovetop: Heat the broth over high heat until it comes to a rapid simmer, then reduce the heat to low. Cover the broth and let it simmer on low for 12 to 24 hours. Skim off the foam on top periodically. You may have to add water occasionally to make sure the ingredients stay covered.
6. To cook broth in a slow cooker: Cover and heat on low for 12-48 hours. I usually do 24 hours
7. Strain and cool the broth: After the broth has darkened to a rich brown color, remove it from the heat and strain through a fine-mesh sieve. Place the stock in a large container and let it cool to room temperature. Once cooled, place it in the fridge to chill. 
8. Scrape off any solidified fat that rises to the top before using.
9. Store in the freezer in containers or glass jars 
10. Reheating bone broth: Reheat your bone broth for a steaming cup you can sip on its own, or use it as a powerful ingredient in your favorite recipes.
