1. Prepare the Broth:

   • Rinse the pork bones under cold water. In a large pot, add the bones and cover with 8 cups of water. Bring to a boil, then reduce heat to simmer for 5 minutes. Drain and rinse the bones to remove impurities.
   • Return the bones to the pot, add the onion, ginger, star anise, cinnamon stick, and salt. Cover and simmer for about 2 hours, skimming off any foam that rises to the surface.

2. Marinate the Proteins:

   • In a bowl, marinate the sliced pork tenderloin with a pinch of salt and pepper for at least 1 hour (or overnight for deeper flavor).

3. Cook the Noodles:

   • In a separate pot, bring water to a boil. Add the rice noodles and cook according to package instructions until just tender. Drain and rinse under cold water to stop the cooking process. Set aside.

4. Prepare the Toppings:

   • In the last 30 minutes of simmering the broth, add the marinated pork to the pot. Cook until the pork is tender, about 15-20 minutes. If using squid, add it during the last 5 minutes.
   • Add the cooked shrimp in the last few minutes just to heat through.

5. Assemble the Hu Tieu:

   • In a bowl, place a portion of noodles. Ladle the hot broth and proteins over the noodles. Top with bean sprouts, green onions, and fresh herbs.
   • Serve with lime wedges and chili sauce on the side for added flavor.

6. Enjoy!

   • Serve hot and enjoy the comforting flavors of Hu Tieu!

Tips

• For a richer broth, you can roast the bones in the oven at 400°F (200°C) for 30 minutes before simmering.
• Customize your Hu Tieu by adding other proteins like beef or fish balls, and adjust the toppings to your taste.
