Method

1. 1
   Place the split trotters and femur sections in a large pot, cover with cold water, and bring to a hard boil. Boil for 10 minutes, then drain and rinse each bone under cold running water, scrubbing away any dark residue or coagulated blood. The bones are ready when they are uniformly pale and the rinse water runs clear.
2. 2
   Return the cleaned bones to the pot. Cover with 3 litres of fresh cold water. Bring to a full rolling boil over high heat. Skim aggressively for the first 30 minutes, removing all grey foam. This is the one step on which the dish lives or dies: maintain a violent rolling boil—never a simmer—for 12 to 18 hours, adding water as needed to keep bones submerged. The turbulence emulsifies collagen and marrow fat into the liquid. The broth is done when it is opaque, milky white, and coats the back of a spoon.
3. 3
   Strain the broth through a fine-mesh sieve, discarding the spent bones. Season with the shirotare (salt tare) and stir in the tori abura (chicken fat) just before service. The finished broth should smell of deep mineral pork with a clean, fatty richness and carry a milky, viscous body.
4. 4
   Prepare the chashu: roll and tie the pork belly, then braise or sear. Slice into rounds of approximately 1 cm. The slices should hold their form but yield immediately under light pressure.
5. 5
   Prepare the nitamago: bring a pot of water to a boil, lower the eggs gently, and cook for exactly 6 minutes 30 seconds. Transfer immediately to iced water. Peel, then marinate in a mixture of 60 ml soy sauce, 60 ml mirin, and 60 ml water for a minimum of 4 hours and up to 12. The whites should be set and lightly bronzed; the yolk should be jammy and yielding at the centre.
6. 6
   Bring a separate large pot of unsalted water to a hard boil. Cook the thin straight noodles for 60 to 90 seconds only — no longer. Drain immediately. The noodles should be firm, with distinct bite; they will continue to soften in the hot broth.
7. 7
   Ladle approximately 350 ml of hot tonkotsu broth into each warmed bowl. Add the drained noodles. Lay two slices of chashu, one halved nitamago, a portion of menma, a sheet of nori, and a pinch of julienned beni shōga on top. Set the condiment station — sesame seeds, garlic press, spice paste — on the table. The bowl should present a clean, restrained arrangement: toppings do not overflow the broth.
8. 8
   To honour the kaedama tradition: when the diner has consumed the noodles, reserve the remaining broth in the bowl. A fresh portion of noodles, cooked 60 to 90 seconds, is transferred directly into that broth. The second serving should taste of broth deepened by the starch carried from the first noodle round.
