Noodles Hard
Classic Tonkotsu Ramen (Pork Bone Milky Broth Noodles)
Pork back bones and trotters boil hard for hours until their collagen and fat emulsify into a milky broth thick enough to feel sticky on the lips. Soaking and blanching the bones beforehand cuts down the porky smell. That rolling boil is the opposite of the gentle simmer used for clear stocks, and it is what separates tonkotsu from an ordinary pork soup. When the pot runs low, it is topped up with hot water, never with a lower flame. Thin, firm noodles, pork belly chashu braised in soy sauce and mirin, a soft-boiled egg, and sliced green onion top the bowl. The chashu slices thin most easily when made a day ahead and chilled, and the eggs marinate in its braising liquid.
