Instructions

  1. Step 1: Place 2 lbs pork bones in a large stockpot, cover with 12 cups water, and bring to a gentle simmer over low heat—never boil vigorously to prevent bitterness.
  2. Step 2: Skim impurities from the surface every 30 minutes for the first 4 hours, then add 3 ginger slices and 3 smashed garlic cloves. Simmer uncovered for 14 more hours, skimming occasionally until broth is opaque and rich.
  3. Step 3: Strain broth through a fine-mesh sieve into a clean pot, discarding solids. Return to low heat and stir in 3 tbsp soy sauce, 2 tbsp mirin, and 1 tsp sesame oil—simmer for 10 minutes to meld flavors.
  4. Step 4: Divide 6 oz sliced chashu pork and 2 peeled soft-boiled eggs between bowls. Pour 1 1/2 cups hot broth over each serving, top with 4 toasted nori sheets, and serve immediately with chopsticks.
