Chop onions, green chillis, curry leaves and ginger to very thin slices.

Make a consistent batter out of gram flour, egg, and a little water. Add the above chopped ingredients and salt to the batter.

Preheat oil in a pan. When the oil is hot enough, pour 1 tbsp of batter (for each vada) to the oil, and deep fry.

Drain the excess oil in the vadas by using a ladle with holes.
