Tonkotsu (豚骨, "pork bone"; not to be confused with tonkatsu) ramen usually has a cloudy white colored broth. It is similar to the Chinese baitang (白湯) and has a thick broth made from boiling pork bones, fat, and collagen over high heat for many hours, which suffuses the broth with a hearty pork flavor and a creamy consistency that rivals milk, melted butter or gravy (depending on the shop). Most shops, but not all, blend this pork broth with a small amount of chicken and vegetable stock and/or soy sauce. The noodles are thin and straight, and it is often served with beni shoga (pickled ginger). In recent years the latest trend in tonkotsu toppings is māyu (sesame oil), a blackish, aromatic oil made from either charred crushed garlic or Sesame seeds. It is a specialty of Kyushu, particularly Hakata-ku, Fukuoka (hence sometimes called "Hakata ramen").
