In a mixing bowl, add 1 cup water and gram flour to make a thick batter. Ensure that there are no lumps.
Mix all the ingredients namely onion juliennes, chopped coriander leaves, carom seeds, turmeric powder, and salt into the mixing bowl with gram flour batter.
Heat oil in a kadai or skillet and wait for it to reach the right temperature. You can check if the temperature is perfect for deep frying by leaving a pinch batter in the oil. It will get fried if the oil is set to the right temperature, else it will stick to the bottom of the skillet or kadai.
Using a spoon drop a tablespoon of prepared onion gram flour batter in the oil. At a time 3 or 4 such tablespoons of batter can be dropped into the oil to fry more pakoras.
Health-conscious people can spread them onto a kitchen paper. Kitchen paper will absorb the extra oil but still it does not serve the purpose to make healthy pakoras ????.
Serve hot with chutney of your choice or tomato sauce or have them plain. I love to have them plain.
