Take a pan over medium flame and boil the milk. Take a bowl and make the custard by mixing the custard powder with 1/2 cup milk and stir until the mixture turns into a smooth blend without any lumps.

Now, put a pan over medium flame and boil the remaining milk. Bring the milk to a boil and add the custard blend to it. Then add sugar to it and switch off the flame.

Stir gently for a minute and keep it in the fridge for 6-7 hours.
