Tonkotsu
豚骨
Tonkotsu means pork bones. Its familiar creamy appearance comes from the way the stock is cooked, rather than being a definition of milk-based soup.
What to notice
A white broth alone does not identify its ingredients. Tonkotsu and tonkatsu, a breaded cutlet, are different words.
Try it with your next bowl
Try the shop’s default noodle firmness first, then compare a refill if one is offered.
