Ingredients

Instructions

  1. Step 1: In a large stockpot, combine 2 kg pork bones, 1.5 L water, 1 chopped onion, 2 sliced carrots, 3 sliced celery, and 4 smashed garlic cloves. Bring to a gentle simmer over medium-low heat for 12 hours, skimming impurities every hour until broth is opaque and gelatinous.
  2. Step 2: While broth simmers, prepare chashu: Place 500 g pork belly in a pot with 10 g sliced ginger, 4 tbsp soy sauce, 2 tbsp rice vinegar, and 500 ml dashi stock. Simmer covered for 90 minutes at 180°F (82°C), then cool in broth and slice 1 cm thick.
  3. Step 3: Strain broth through a fine-mesh sieve into a clean pot. Add 3 tbsp shoyu and 1 tbsp sesame oil, simmering for 15 minutes until flavors meld. Cook 200 g ramen noodles in boiling water for 3 minutes, then rinse under cold water.
  4. Step 4: Divide noodles into bowls, top with 2 slices chashu, 80 g bamboo shoots, and 20 g green onions. Pour 400 ml hot broth over ingredients, then garnish with a soft-boiled egg.
