Traditionally eaten with boiled rice for dinner, although it can be eaten on its own. My mum makes this specially for someone in the family who is feeling ill or down in the dumps! The meat should just fall off the bone. I know the list of spices may appear daunting if you don't have them, but once you buy them they can be stored in the cupboard and used to make other things like curries from scratch.
If you prefer a thicker sauce, you could melt a knob of butter or use around a tablespoon sesame oil; add a tablespoon plain flour to make into a paste and chuck in the soup 5 minutes before finished cooking time. This dish can be kept in the fridge and tastes even better the next day!
