Time Out says
Before you start, you must know that eating a dish of sup tulang is not going to be a clean and swift affair. It's messy, sloppy and absolutely a delight to fully partake in a meal. There's a lot of scooping, digging, knocking and also sucking. The name translates to 'bone soup' and consists of beef bone cuts with a sweet and spicy red stew of mutton stock, tomatoes, ginger, chillies and other herbs. The best part – and mandatory too – is knocking out or sucking up the buttery bone marrow from the bones.
