Take a heavy bottomed pan and add 2 tbsp water in it. Water prevents the milk from burning.
Add 3 litre milk.
Leave the milk to boil.
When milk begins to boil, add 450 gram sugar.
Mix and don't let malai form on the surface of milk.
Also keep on scrapping the sides of the pan where the malai is sticking.
Do stir occasionally to prevent milk from burning.
After some time milk will begin to change it's colour. Keep boiling and stirring occasionally.
A stage with comes when milk will begin to thicken like a porridge.
Add 1 tsp cardamom powder and 3 tsp desi ghee. Give it a good mix.

Lastly a mass is formed which will start leaving the sides of the pan.
Immediately transfer it to a greased pan or cake tin or tray.
Sprinkle melon seeds over the top.
Let it cool down completely.
Cut into slices and enjoy.
