A Japanese broth made from pork marrow, typically served with ramen:[as modifier]:I ordered the tonkotsu ramen...
The broth is ideally salted and as rich and meaty as one might hope for in tonkotsu.
This special stock is almost as thick and fully flavoured as creamy tonkotsu.
The tonkotsu broth here is simmered for 20 hours.
Usage
The words tonkotsu and tonkatsu are often confused. Tonkotsu means ‘a Japanese broth made from pork marrow’, whereas tonkatsu means ‘a Japanese dish of pork coated in breadcrumbs and fried’.
