Which brand ? Hahaha... you are so sweet !! I think the last bag of rawa was Raj-something. It doesn't matter, so long as it does not have any bugs crawling in it. When it is thick, you have to dilute the batter, as well as devise a means to spray it thinner. I taught my child to use a pump sprayer that one can buy in a garden shop (or from amazon).... there are also shampoo bottles (you can wash and repurpose) for this use. Make a chutney of ginger, pepper, salt, curry leaves, asafoetida, and yoghurt. A smooth chutney is key to an unclogging spray. Mix a little bit of this chutney with water, rawa and rice flour (in the proportions suggested by one of those youtube video guys) in one of these spary bottles. Hold the neck and shake well, then set the nozzle at a wide spray, and spary onto a very very hot oiled tawa (or waffle iron)... no need to fill all the holes... just make sure that the surface is "generally covered". After a minute or so (if you are using a flat tawa and not waffle iron) slide a flipper over the surface to spread out the excess. If you are using a waffle iron, sprinle some oil on the lid, and close the lid. Listen to a 3 minute song on your ear buds before you open the lid. Hint: You may also enlarge the spray nozzle hole by inserting a tiny philips screwdriver into the nozzle and rotating it to make it bigger.
