"Wanted to make tonkotsu without big amount of bones for one serving. Pig trotters consist of bone, meat, and cartilage, so, it's liquified. I used liquified pork and some bones for flavor with some chicken base."
Cut bones and fat from pork chop and cut meat into small pieces. Place bone, fat, and meat in a saucepan; add water, onion, chicken base, and garlic. Bring liquid to a boil, reduce heat to medium-low, cover saucepan, and simmer, adding more water every hour, 5 to 6 hours.
Strain broth into a bowl and separate bones from the meat. Put meat and 1/2 of the broth in a blender; blend. Return blended broth to broth in saucepan and mix well.
