In a large mixing bowl add sliced onions, chopped curry leaves, coriander leaves, green chillies, powdered coriander seeds, salt and turmeric powder. Mix it well with your hands. Onion when mixed with salt oozes out water. This water itself is enough to prepare the batter. (It looks as below)
Now add chickpea flour, rice flour and baking soda, mix well with your hands. Do not add additional water.
Heat a heavy bottomed kadai adding cooking oil. When oil gets heated, take a lump of pakoda batter and drop small amount of it in to the water. Making shape is not necessary. Onion pakodas are actually shapeless.
Fry the pakodas in low flame till golden brown and drain them on tissue paper. Make pakodas in batches with rest of the batter.
Serve onion pakodas with a cup of hot tea....It tastes yummmmmmmmmmmmm.......
