Hi everyone , So i have heard a lot about opos in the past year and follow that fb group of RK . But for some reason I never find enough courage to ask anything there . I have two prestige non stick pressure cookers . one is small 3.3 litre handi style and other is a big one almost 5 -6 litre straight wide mouth type . So I really dont want to spend on buying that magic pot for now since both the cookers are new , barely used . I really want to try opos with the small PC . Kindly help me with the usage . As in how to begin with for an absolute novice. I think it needs some standardization . I would use it on normal 4 burner gas stove you find in apartments here. Thank you very much for your help.
