Sprinkle the saltwater slowly over the rice flour and mix well.
Continue this process till the flour becomes wet and smooth.
:-Do not use too much water. (The perfect stage to stop the process is to take a handful of wet flour in the hand, just press it and open the fist. If the flour remain as a solid chunk without breaking or splitting apart, you can stop the process.)
Add little grated coconut into the prepared flour and mix well.
:- To make soft puttu, just grind the wet flour in a mixer.
For preparing puttu, put a layer of grated coconut into the puttu kutti (puttu maker) followed by the plantain mix and rice flour and then again a layer of plantain and finally a layer of grated coconut.
Steam it for 5 to 8 minutes until the steam passes from the top of the puttu kutti.
