Instructions

  1. Prepare the Bones and Brisket: In a medium cooking pot, fill with water and bring to a boil. Add pork bones and cook over high heat for 10 minutes to remove impurities. Drain and rinse the bones with cold water. Similarly, quickly blanch the brisket in the same pot, then drain and rinse. Set both aside.
  2. Toast the Spices: In a dry pan over medium heat, toast ginger slices, smashed lemongrass stalks, garlic cloves, cinnamon stick, and whole cloves until fragrant. Tie the cinnamon stick and lemongrass into a sachet using kitchen twine; place the other spices into a separate sachet.
  3. Simmer the Broth: In a large pot, bring 7 quarts of water to a boil. Add pork bones and brisket, bring back to boil, then reduce heat to maintain a simmer. Add spice sachets and lemongrass stalks. Simmer over medium-high heat for 45 minutes, skimming off impurities occasionally. Then add the whole white onion and continue simmering for another 45 minutes.
  4. Make Oil and Seasoning Mixtures: In a stainless steel pan over medium-low heat, heat pure sesame oil and annatto seeds for 5 minutes. Strain the oil to remove annatto seeds and return the infused sesame oil to the pan. Add minced garlic and shallots, sauté for 3-4 minutes, then set aside. In the same pan, sauté additional seasoning ingredients including sesame oil, red pepper flakes, minced lemongrass, and shrimp paste for 3-4 minutes; set aside.
  5. Season the Broth: Remove brisket from the pot and allow it to cool; discard other solids from the broth. Add about 8 cups of hot water to the pot. Pour in the prepared oil mixture followed by the seasoning mixture. In a small bowl, dissolve chicken bouillon, kosher salt, and fish sauce into half a cup of hot broth, then return this mixture to the pot. Simmer the broth for another 20 minutes. Keep the broth on low heat until serving.
  6. Prepare Meat and Noodles: Slice the brisket thinly. Quickly blanch beef tenderloin slices in hot water, then wrap in plastic wrap to keep warm. Cook Hue noodles according to package instructions and keep warm.
  7. Assemble the Soup: In each serving bowl, place half the amount of noodles, arrange sliced brisket and tenderloin on top, and garnish with thinly sliced white onion and chopped green onion. Ladle hot broth into the bowl to cover the noodles and meat completely.
  8. Serve: Offer shredded water spinach, banana flower, beansprouts, fresh oregano leaves, lime wedges, and optionally red cabbage on the side for garnish. Serve with a dipping sauce made of fish sauce, Thai chilies, and shrimp paste. Enjoy your authentic Bun Bo Hue!
