Instructions

1. Place 6 pounds of beef knuckle marrow and neck bones in a large pot, cover with cold water, and bring to a hard boil for 10 minutes.
2. Pour off the dirty water, scrub the bones under cold tap water, and scrub the pot.
3. Return cleaned bones to the clean pot, add 1 pound brisket and 1 pound oxtail, cover with 6 liters of fresh cold water, and bring to a bare simmer.
4. Skim the gray foam every 15 minutes for the first hour.
5. Char 2 large yellow onions cut in half and 1 hand of fresh ginger sliced lengthwise directly over an open gas flame or under a broiler for 8 minutes total until surfaces are deeply blackened and blistered.
6. Rinse the burnt skin off under cold water.
7. Drop the charred onions and ginger into the simmering broth at the one-hour mark.
8. Lower the heat so the broth never boils above a gentle bare simmer.
9. In a dry pan over medium heat, toast 4 whole star anise, 2 cinnamon sticks each 3 inches long, 6 whole cloves, 1 tablespoon coriander seeds, 2 black cardamom pods, and 1 teaspoon fennel seeds for 2 to 3 minutes until the oils release.
10. Tie all toasted spices in a square of cheesecloth and drop the spice sachet into the broth at the two-hour mark.
11. Simmer the broth for 10 more hours (for a total of 12 hours).
12. At hour eleven, add 1/4 cup fish sauce, 2 ounces of yellow rock sugar broken into small pieces, and 2 tablespoons of salt to the broth. Taste and adjust salt by the half teaspoon.
13. Strain the entire broth through a fine cheesecloth-lined strainer; discard the bones.
14. Keep the brisket; slice it across the grain a quarter inch thick after it cools for 5 minutes.
15. If using dried noodles, soak for 10 minutes in warm water, then blanch for 60 seconds in boiling water, drain, and divide into 4 wide flat phở bowls. (Skip if using fresh noodles).
16. Slice 1 pound of eye-of-round beef (frozen 30 minutes first) paper-thin, 1 to 2 millimeters, with a sharp knife at a 30-degree angle.
17. Arrange 12 thin slices of raw beef over the noodles in each bowl, topped with the cooked brisket slices, thin slivers of yellow onion and green onion, and fresh chopped cilantro.
18. Bring the strained broth back to a rolling boil at 212°F (100°C).
19. Ladle 3 full cups of boiling broth directly onto the raw beef in each bowl.
20. Serve immediately with a small side plate of fresh thai basil leaves, 2 quartered limes, 2 thin slices of fresh red chili, and a small dish of chili-garlic vinegar.

• Phở originated in Nam Định province in northern Vietnam in the early 1900s, with historians debating its naming origins from French or Cantonese influences.
• The Hanoi-style Phở Bò distinguishes itself as clearer and cleaner than its sweeter, herbier Southern Vietnamese counterpart.
• Achieving a clear, amber broth requires blanching beef bones for ten minutes in a hard boil, then scrubbing them clean before the main simmer.
• Yellow onions and fresh ginger are charred over an open flame or broiler for eight minutes until deeply blackened and blistered to give the broth its signature golden color and faint sweet smoke.
• Eight specific aromatic spices—star anise, cinnamon sticks, cloves, coriander seeds, black cardamom pods, and fennel seeds—are toasted dry for two to three minutes and added to the broth in a cheesecloth sachet at the two-hour mark.
• The broth must simmer for a full twelve hours at a gentle bare simmer, as boiling will muddy the clarity.
• Seasoning at hour eleven involves 1/4 cup fish sauce, 2 ounces yellow rock sugar, and 2 tablespoons salt, aiming for a balance of salty, slightly sweet, and deeply beefy flavors.
• Eye-of-round beef is prepared by freezing it for thirty minutes, then slicing it paper-thin (1-2 millimeters) at a 30-degree angle.
• Raw, paper-thin slices of beef are cooked medium-rare in under ten seconds by ladling 212°F (100°C) boiling broth directly over them in the bowl.
• Hanoi-style Phở is served with deliberately spare accompaniments: fresh Thai basil, lime, red chili, and chili-garlic vinegar, notably excluding hoisin, sriracha, or bean sprouts.
