Take a bowl mix together ginger garlic paste, red chilly powder, black pepper powder, lemon juice, color, salt, coriander powder and whisked thick curd. Now add the chicken pieces. Cook the bowl and marinate them for 2 – 3 hours in a refrigerator.
Before start frying to the marinated chicken pieces add a beaten egg and then cornflour and rice flour. Mix well so that all the chicken pieces are well coated with the flours. Make sure no lumps are formed.
Heat oil in a kadai. Once it becomes hot drop the chicken pieces one by one in the oil and fry them till golden crisp. Do not put too many pieces but fry them in small batches so that all pieces are cooked evenly. Keep turning with a slotted spoon once in a while.
Take them out on a paper towel and keep aside.
In a separate pan heat 1 tblsp of oil.
When it is hot add the curry leaves and chopped garlic. Once the garlic gets slightly golden brown add the slit green chillies.
To this add the tomato ketchup and add the fried chicken pieces. Mix well.
Dish out the pieces in a serving platter and garnish with thin sliced onions and lemon wedges and coriander leaves.
