Chicken 65

The name in itself is mystical. What does the 65 symbolize?
The item number in the menu card of the army mess where it was first introduced?
The age of the chicken in days which should be used to prepare the dish?
The year in which it was first created?
Whatever is there in a name, the dish is tasty and a family favourite.
Here is my recipe for Chicken 65.
Chicken, preferably boneless, cut into small pieces - 1/2kg
Red chilli powder - 2 Tbsp
Turmeric powder - 1/2tsp
Garam Masala - 1 Tbsp

Salt - to taste

Besan (Gramflour) - 2Tbsp
Curd - 2 Tbsp
Soy sauce - 1Tbsp
Curry leaves, roughly cut - a few
Green chillies, slit - 3 Nos
Marinate the chicken pieces in the rest of the ingredients for 2-3 hours in refrigerator.
Deep fry in hot oil and serve hot with onion rings, Lemon wedges and cucumber.
