Take 2 tbsp of water in a heavy bottomed pan which will help the milk not to stick to the bottom of the pan.
Add milk and let it boil.
Do stir at intervals so that cream/malai shouldn't form on the surface of the milk and edges of the pan.
When milk boils, remove the pan from the heat and let milk cool down a bit for 5 minutes.
Take a ladle full of milk and add 1 tbsp of vinegar water in it.
Stir the ladle in the milk.
Keep on repeating the process until milk curdles and greenish water and milk solids are seen separately.
Sieve the curdled milk through a sieve lined with muslin cloth so that milk solids (chenna) gets collected in the cloth.
Pour some water over the chenna so that smell and taste of vinegar washes away.
Squeeze the cloth so that excess water is released.
Place the chenna carrying cloth in a towel and keep aside for 1 hour so that towel will soak all the remaining moisture from chenna.
Till the time, take very hot water in a bowl and add jaggery.
Stir and leave the jaggery to melt till needed.
Put the chena in a wide tray or place.
Mash it for 5-7 minutes with the upper side of your palm. But do not over do it.
Lastly mix corn flour in the chenna and turn the chenna into a dough.
Make equal sized 10 balls with no cracks.
Sieve the jaggery water in a pan.
Add green cardamoms.
Let the water come to rolling boil.
Add all the balls in the jaggery water, but one by one.
Cover and let it cook for 15 minutes on high heat so that rolling of water shouldn't come down.
Just for once or twice, remove the lid and pour boiling water over balls without touching them.
Take the pan off the heat and let it come to room temperature.
Enjoy hot, at room temperature or cold. We love it chilled.
