Hi haldi, you're right there is a tava but, this is a different thing. The tawa is specifically made for cooking curries on, it's bigger and thicker than the tava we use for making chappatis on, if you look carefully at the picture I posted you can see the thickness is greater. Tavas are usually only a few millimetres thick and almost flat and that's what was bugging me because I couldn't envisage how you would cook a curry on one.
