Chop the cilantro into small bits. I like to add some soft stems too, they give a great flavour.
In a mixing bowl, add all the steaming ingredients except water. Mix well, then add 1 cup water. Make a batter that is fairly thick. Add as much of the half cup water as required.
Add a tsp of oil and spread it in a microwave safe flat bowl. Add the prepared mixture and microwave for 2 minutes with the lid on.
Cook for more time if the surface does not become firm in 2 minutes. The sides will shrink too and a toothpick inserted in the centre comes out clean.
Once done, remove on a plate or tray. Let it cool. Then cut the vadi into cubes or diamonds. They taste amazing as is.
Else, heat oil in a pan, add green chilli, curry leaves and sesame seeds. Shallow fry the kothimir vadi.
Serve immediately with green cilantro chutney and tomato ketchup.
