Viet Hapa Pho

For the soup

• 2 medium yellow onions, halved
• 1 4-inch piece of ginger, quartered
• 6 pounds beef bones
• 1 pound oxtail
• 5 quarts water
• 1/2 cup fish sauce
• 2 bay leaves
• 1 cinnamon stick
• 1 tablespoon black peppercorns
• 3 pieces star anise
• 6 cloves, whole
• 2 tablespoons brown sugar
• Salt and pepper, to taste
• 1 packet rice sticks (pho noodles)
• 1/2 pound beef tenderloin, thinly sliced

Garnishes

• Bean sprouts
• Cilantro
• Lime wedges
• Thai basil

1. Over the open flame of a burner, char onion and ginger halves until fragrant and blackened.
2. In a 10 to 12-quart stockpot, place beef bones, onion, ginger and oxtail. Cover with 5 quarts of cold water (bones should be completely covered. If not, add more water).
3. Bring beef bones and water to a boil over high heat, then reduce heat to medium-low and simmer for 1-1/2 hours, skimming all impurities from bones that float to the surface.
4. Add cinnamon stick, star anise, bay leaf, cloves, peppercorns, fish sauce and sugar to broth. Continue to simmer for another 1-1/2 to 2 hours, skimming surface of broth as needed.
5. Taste broth. Depending on how much marrow is in the bones you use, you may need to simmer for longer and reduce the liquid to get that full-bodied beef taste. Remove bones and spices from broth. Season with salt and pepper.
6. (This is an optional step.) When broth is to your liking, cool broth and place in refrigerator overnight. In the morning, take pot out of fridge and skim fat off of surface of broth.
7. To assemble: Reheat broth to a boil. Soak pho noodles in a bowl of water until soft. Drain.
8. Heat water in a 4- to 5-quart pot. When water comes to a boil, add soaked noodles. Cook for 3 to 5 minutes, or until noodles are soft. Drain, and portion noodles into bowls.
9. Place thinly sliced raw tenderloin on top of noodles. Ladle broth over meat and noodles. Top with garnishes and serve hot.
