This is a slow-cooked Indonesian soup that will taste very different in Indonesia depending on which area of the country you have it.
It’s also delicious and one of my brother’s favorites, both to eat and cook.
He tends to prefer to quickly grill the oxtail before adding it to the broth, which in Indonesia would be Sop Buntut Bakar. It is also perfectly acceptable to just slow cook it in the broth.
They give slightly different textures and flavors, so you can experiment.
Be ready to substitute the oxtail for osso bucco or whatever cut of meat is available and good value. Oxtail is not very common outside Asia. If you do, osso bucco will tend to taste slightly meatier and less fatty, but delicious also.
