•	500 grams of beef shank or beef brisket, thinly sliced
•	300 grams of pork hock or pork trotters, cut into chunks (optional)
•	200 grams of beef bones
•	1 onion, peeled and halved
•	2 inches ginger, sliced
•	4-5 stalks lemongrass, cut into 3-inch pieces and bruised
•	3-4 cloves garlic, minced
•	2-3 tablespoons shrimp paste or fish sauce
•	2-3 tablespoons chili paste (adjust to taste)
•	1 tablespoon annatto seeds (optional, for color)
•	1 tablespoon sugar
•	1 tablespoon vegetable oil
•	Salt and pepper to taste
•	Thick rice noodles (bún)
•	Fresh herbs (Thai basil, cilantro)
•	Bean sprouts
•	Lime wedges
•	Sliced chili peppers (optional)
•	Sliced onion and green onion (optional)
Instructions:
1.	Prepare the Broth:
•	In a large pot, add the beef bones, beef shank (or brisket), pork hock (if using), onion halves, ginger slices, and lemongrass stalks. Cover with water and bring to a boil. Skim off any scum that rises to the surface.
2.	Cook the Broth:
•	Reduce the heat to low and simmer for 2-3 hours, until the meats are tender and the broth is flavorful. Add water as needed to maintain the level.
3.	Prepare the Seasonings:
•	In a small saucepan, heat the vegetable oil over medium heat. Add minced garlic and cook until fragrant.
•	Add shrimp paste (or fish sauce), chili paste, annatto seeds (if using), sugar, salt, and pepper. Stir well and cook for another minute. Set aside.
4.	Prepare the Noodles:
•	Cook the thick rice noodles (bún) according to package instructions. Drain and rinse under cold water to stop cooking. Set aside.
5.	Assemble the Soup:
•	Remove the beef shank (or brisket), pork hock (if using), and beef bones from the broth. Slice the beef thinly.
•	Strain the broth through a fine sieve to remove solids. Return the broth to the pot and bring it back to a simmer.
6.	Serve:
•	To serve, divide the cooked noodles into bowls. Top with slices of beef, and pork hock (if using), and ladle hot broth over the noodles.
•	Garnish with fresh herbs (Thai basil, cilantro), bean sprouts, lime wedges, sliced chili peppers (if desired), and sliced onion/green onion.
Note:
•	Bún Bò Huế is traditionally spicy, so adjust the chili paste to your preferred level of heat.
•	This soup is best enjoyed hot and fresh, with the noodles absorbing the flavorful broth.
