  • 2 or 3 limes, cut into wedges
  • 12 sprigs mint
  • 2 or 3 Thai or serrano chiles, thinly sliced
  • Leaves from 1 head romaine lettuce, halved lengthwise and cut crosswise into 1/4-inch-wide ribbons (optional)
  • 3 cups bean sprouts (about 1/2 pound) (optional)
  • 1 cup thinly sliced banana blossom bract (leaf), soaked in acidulated water, massaged with warm water, and drained well (optional; see Note)
  • Spoonful of fine shrimp sauce (optional)

Method

  • To achieve a clear broth, first parboil and rinse the beef bones.
  • Put them in a stockpot (about 12-quart capacity) and add cold water to cover.
  • Bring to a boil over high heat and boil for 2 to 3 minutes to release the impurities.
  • Dump the bones and water into the sink, and then rinse the bones with water to wash off any residue.
  • Set the bones aside.
  • Scrub the stockpot, dry it, and set aside.
  • Lightly season the beef shank and the pork leg with salt and pepper and set aside.
  • Add the oil to the stockpot and heat over medium-high heat.
  • Add the onions and cook, until fragrant, about 1 minute.
  • Add the annatto and stir to release its color.
  • When the onion is yellow-orange, push it to the side and add the beef shank and pork leg.
  • Briefly sear the meat to lightly brown.
  • Pour in the water and add the reserved bones and the pork hock.
  • Bring to a boil over high heat and lower the heat to a gentle simmer.
  • Use a ladle or large, shallow spoon to skim off any scum that rises to the top.
  • Add 1 1/2 tablespoons salt, the fish sauce, rock sugar, and lemongrass.
  • Simmer gently, uncovered, for 1 hour.
  • Transfer the pork leg and hock to a bowl of cold water to cover.
  • Let soak for 10 minutes to prevent it from drying out and turning dark.
  • Drain the meat, set aside on a plate to cool completely, then cover with plastic wrap and refrigerate.
  • Meanwhile, simmer the broth for 1 hour longer after removing the pork, for a total of 2 hours.
  • When the broth is done, remove the beef shank, soak it in cold water as you did the leg and hock, and then drain, cool, and store with the pork.
  • Strain the broth through a fine-mesh sieve (or a coarse-mesh sieve lined with cheesecloth) positioned over a pot.
  • Discard the solids.
  • Use a ladle to skim as much fat from the top of the broth as you like.
  • (Or, let cool, refrigerate overnight, lift off the solidified fat, and reheat before continuing.)
  • To make the chile-lemongrass mix, put the oil, chile flakes, garlic, and lemongrass in a small saucepan and bring to a gentle simmer over low heat.
  • Let bubble and sizzle for 5 minutes, swirling or stirring occasionally.
  • Remove from the heat and stir in the sugar and fish sauce.
  • Transfer to a small serving bowl and let cool.
  • To finish the broth, scoop out a little into a cup, stir the shrimp sauce into the cup, and pour the mixture through a finemesh sieve into the broth.
  • Depending on your taste, stir in one-fourth to one-half of the chile-lemongrass mix, saving the rest for serving at the table.
  • Taste and adjust the flavor with additional salt, if necessary.
  • There should be about 4 quarts (16 cups) broth.
  • To reheat the noodles, fill a large pot with water and bring to a rolling boil.
  • Meanwhile, cut the beef and pork leg across the grain into slices about 1/16 inch thick.
  • For the best results, make sure they are cold.
  • Set the beef and leg pork aside.
  • Put the pork hock pieces in the broth.
  • Have ready the noodles, yellow onion, scallions, and Vietnamese coriander.
  • Arrange the garnishes on a plate or put them in small dishes and put on the table.
  • To ensure good timing, bring the broth to a simmer over medium heat while you are assembling the bowls.
  • When the water has reached a boil, place a portion of the noodles on a vertical-handle strainer (or mesh sieve) and dunk the noodles in the water.
  • After 5 to 10 seconds, pull the strainer from the water, letting the water drain back into the pot.
  • Empty the noodles into a bowl and repeat with the remaining portions, while proceeding to assemble each bowl as the noodles are added.
  • Top each bowl of noodles with the beef and pork, arranging the slices flat.
  • Place a mound of yellow onion in the center and then shower some scallion and Vietnamese coriander on top.
  • Bring the broth to a rolling boil.
  • Ladle 2 cups broth into each bowl, distributing evenly to warm the ingredients and including a piece of pork hock with each portion.
  • Serve immediately with the garnishes and the remaining chile-lemongrass mix.
