what is tonkotsu broth

Tonkotsu broth is a soup broth that is used in tonkotsu ramen, a Japanese noodle dish that originated in Fukuoka, Fukuoka Prefecture on the Kyushu island of Japan. The broth is made by boiling pork bones in water for a significant amount of time, up to 18 hours, which extracts all the goodness of the pork and turns the broth creamy. The broth is typically cloudy in appearance and can include additional ingredients such as onion, garlic, spring onions, ginger, pork back fat, pigs trotters, oil, and chicken carcasses. The traditional preparation method for the ramen noodles used in tonkotsu ramen is for the noodles to be hard in the center, but some ramen shops allow customers to select the level of firmness for the noodles. Tonkotsu broth is the foundation to a great bowl of ramen, and you can make just about any tonkotsu-style ramen with it.
