Ingredients:
- 2 pounds (900 g) pork bones (neck bones or marrow bones)
- 1 large onion, halved
- 5 cups (1.2 L) water (or more as needed)
- 2 tablespoons fish sauce
- 1 tablespoon salt
- 1 tablespoon sugar
- 1 pound (450 g) ground pork

- Lime wedges
- Thinly sliced chili peppers (optional)
Instructions:
- Blanch pork bones in boiling water for 5 minutes, then drain and rinse.
- In a large stockpot, combine blanched bones, halved onion, and water. Bring to a boil, then reduce heat and simmer for 2 hours, skimming fat and impurities as necessary. Season with fish sauce, salt, and sugar.
- In a mixing bowl, combine ground pork, minced garlic, shallots, black pepper, and fish sauce. Mix well until mushy and shape into meatballs, about 1 inch in diameter.
