De-shell the prawns and wash them properly.
Marinate the prawns by applying red chili powder, turmeric powder, black pepper powder, lime juice, minced ginger and garlic, egg white, corn flour and salt and keep aside for 20 to 30 minutes.
In a kadai or deep-frying pan, add enough oil and deep fry the prawns in batches of 5 for 3 to 5 minutes on a medium-low flame.
Drain the deep-fried prawns on kitchen paper.
Switch off the flame and remove excess oil from the pan.
In the same pan, add 1 tablespoon oil and sauté the curry leaves and green chili.
Add the fried prawns and mix well.
Serve hot and enjoy.
