Ingredients:
- 2 pounds beef shank, bone-in, cut into chunks
- 1 pound beef trimmings or ground beef
- 6 cups cold water
- 1 large onion, roughly chopped
- 2 carrots, roughly chopped
- 2 celery stalks, roughly chopped
- 3 garlic cloves, crushed
- 1 bouquet garni (1 bay leaf, 4 sprigs of fresh thyme, 2 sprigs of parsley tied together)
- Salt, to taste
- Freshly cracked black pepper, to taste
- 2 large egg whites
- 1/2 cup finely grated carrot
- 1/2 cup finely chopped celery
- 1/2 cup finely chopped onion
- 1 tablespoon lemon juice
Instructions:
- Combine beef shank, trimmings, and water in a stockpot. Add onion, carrots, celery, and garlic. Bring to a boil, skimming off any scum that rises to the surface.
- Reduce heat and add bouquet garni. Simmer uncovered for 2 to 3 hours, or until the beef is tender and flavor is concentrated.
- Pour the broth through a fine mesh sieve into a large bowl, discarding solids.
- In a separate bowl, whisk together egg whites, grated vegetables, and lemon juice. Mix the clarified mixture into the cooled broth.
- Slowly reheat the broth over low heat, stirring gently. Once the mixture begins to form a raft, stop stirring and let it simmer for 10-15 minutes. Carefully strain through a fine mesh sieve lined with cheesecloth to remove solids.
- Adjust seasoning with salt and pepper as needed. Serve hot in warmed bowls.
