Instructions

  1. Step 1: Place 2.5 kg pork bones and 12 L water in a large stockpot, bring to a gentle simmer over medium-low heat, skimming off impurities for 15 minutes until clear.

  4. Step 4: Cook 400 g fresh noodles in boiling water for 2 minutes, drain, and divide into bowls.
  5. Step 5: Top noodles with 150 g sliced bamboo shoots, 4 soft-boiled eggs (peeled and halved), and 3 finely sliced green onions, then pour hot broth over until fully covered.
