In a bowl, mix chicken pieces with ginger-garlic paste, curd, turmeric powder, red chili powder, garam masala, salt, egg, and rice flour. Let it marinate for at least 30 minutes.
Heat enough oil in a deep pan for frying.
Fry the marinated chicken pieces in batches over medium heat until they are golden and crispy. Drain on a kitchen towel.
In a separate pan, heat 1-2 tbsp oil. Add curry leaves and slit green chilies. Sauté until they crackle.
Add the fried chicken pieces into the pan with curry leaves and green chilies. Toss well to coat the chicken with the tempering.
Taste and add a sprinkle of salt or chili powder if needed for extra flavor.
Garnish with a few more fried curry leaves and serve hot with lemon wedges or as a snack.
