Ingredients:
- 3-4 pounds (1.3 - 1.8 kg) beef bones (knuckle, marrow, or femur), preferably organic and grass-fed
- 1-2 chicken carcasses (optional)
- 1 large onion, roughly chopped (approx. 150g / 5.3 oz)
- 2 carrots, roughly chopped (approx. 120g / 4.2 oz)
- 2 celery stalks, roughly chopped (approx. 100g / 3.5 oz)
- 4 cloves garlic, smashed
- 1 inch (2.5 cm) piece of ginger, peeled and sliced
- 1 tablespoon apple cider vinegar (15 ml)
- 1 teaspoon black peppercorns (5 ml)
- 2 bay leaves
- A handful of fresh parsley or thyme stems (optional)
- 12 cups (3 liters) filtered water
Instructions:
- Preheat oven to 400°F (200°C). Spread bones on a roasting pan and roast for 20-30 minutes, or until lightly browned. This deepens the flavour.
- Place roasted bones (or raw bones, if skipping roasting) into the stockpot.
- Add the onion, carrots, celery, garlic, ginger, peppercorns, bay leaves, and any optional herbs.
- Pour 1 cup (240 ml) of water into the roasting pan and scrape up any browned bits from the bottom. Add this liquid to the stockpot.
- Pour in the apple cider vinegar.
- Pour in the filtered water, ensuring the bones and vegetables are submerged.
- Bring the mixture to a boil, then immediately reduce heat to a very low simmer. Skim off any foam or impurities that rise to the surface.
- Cover and simmer for at least 12 hours, or up to 24 hours.
- Let the broth cool slightly. Carefully strain the broth through a fine-mesh sieve (lined with cheesecloth for extra clarity, if desired) into a large bowl or pot. Discard the solids.
- Allow the broth to cool completely before transferring it to airtight containers. Refrigerate for up to 5 days, or freeze for up to 3 months.
