Make a fine chutney of fresh grated cocunut, green chillies, coriandar leaves, salt and a pinch of sugar.
Now make a ball out of the mashed potatoes with a help of little water so that the mashed potatoes do not stick on the palm and mould it into shape of a 'katori'('flat bowl').
Place one half of the egg (yolk facing outside) into the 'katori'and apply a thin layer paste of green chutney over it.
Now you need to need to cover the stuffing by bringing together the ends of the potato 'katori'. You will see a oval shaped ball in your palm. Roll this ball in the rice flour thoroughly but carefully. Now it is ready for a deep fry.
Pour the oil in the frying pan only after it is pre-heat so that it allows the ball to roll in the pan freely.
Do not fiddle the pattice atleast for the first two minuites. Fry them till they turn golden yellow. Serve hot with tomato ketchup.
