Cut chicken into pieces. Clean, wash and marinate the chicken with soy sauce, 1/8 teaspoon colour, lime juice and salt for at least 2 hours.
Grind the ginger, garlic and onions to a fine paste. Heat a pan and add oil. Fry the chicken pieces till golden brown and drain them in an absorbant paper.
In the remaining oil, add the ginger-onion paste and saute till the raw smell goes off.
Add the chilli powder, vinegar, MSG, pepper powder, tomato sauce, remaining colour and the fried chicken along with salt and mix well.
Cook till the gravy thickens.
Remove from fire and transfer to a serving plate. Garnish with chopped spring onion.
