Japanese Tonkotsu Ramen Broth
Japanese Tonkotsu Ramen Broth is a rich, creamy pork bone soup that forms the heart of Hakata-style ramen from Fukuoka. It's made by simmering pork bones for many hours until the collagen and marrow break down, creating a signature opaque, milky-white broth. Typical ingredients include pork bones, aromatics like ginger and garlic, and sometimes chicken or dashi for added depth.
