What you'll need
- Enameled Dutch oven — Simmers evenly; the non-reactive enamel keeps flavors clean.
- Immersion blender — Blend hot soups right in the pot — no dangerous transfers.
- Fine-mesh strainer — Strain stocks and purées to a restaurant-quality finish.
Instructions
- Place pork bones and chicken carcasses in a large pot, cover with water, and boil for 10 minutes to remove impurities; drain and thoroughly scrub the bones.
- Return the cleaned bones to the pot with 6 quarts fresh water, the ginger, garlic, and mushrooms. Keep the pot at a steady rolling boil, partially covered, for 6–8 hours, topping up with water as needed to keep the bones submerged — the hard boil is what emulsifies the fat and collagen into an opaque, creamy white broth.
- Strain the broth through a fine-mesh sieve, discarding all solids.
- Bring the strained broth back to a simmer and whisk in the miso paste, coconut aminos, and chili flakes until fully incorporated. Taste and adjust seasoning.
- Cook the buckwheat noodles per package instructions, drain well, and divide among four deep serving bowls.
- Ladle the hot spicy tonkotsu broth over the noodles, then top with halved soft-boiled eggs, scallions, and a light drizzle of avocado oil.
