Ingredients

Instructions

  1. Step 1: Place pork bones in a large stockpot, cover with cold water, and bring to a gentle boil over medium-high heat; skim off any foam that rises to the surface for 15 minutes.
  2. Step 2: Add carrots, onion, ginger, garlic, and soaked shiitake mushrooms; reduce heat to low and simmer uncovered for 12 hours, skimming foam every 30 minutes until broth turns opaque and milky.
  3. Step 3: Strain broth through a fine-mesh sieve into a clean pot, discarding solids; return broth to low heat and stir in dashi powder, sesame oil, soy sauce, and mirin until fully dissolved (about 2 minutes).
  4. Step 4: Bring a separate pot of salted water to a rolling boil, add ramen noodles, and cook for 3 minutes until al dente; drain and divide between two bowls.
  5. Step 5: Ladle hot broth over noodles, top with soft-boiled eggs, narutomaki, and green onions; serve immediately while broth is steaming hot.
