Add whole milk, condensed milk and milk powder into a heavy bottom non-stick pan and bring it to a boil. Once the milk comes to a boil, reduce the heat to low.
Add condensed milk and milk powder to the pan and mix well.
Let the milk cook on low heat until it is reduced to almost ½ of the initial volume. Stir frequently at regular intervals to avoid scorching the bottom of the pan.
Add the almond cashew pistachio powder to the milk pan and mix well.
Switch it off and let it cool completely.
Remove the pan from heat and allow the mixture to cool down completely.
Once cool completely and add puréed mango, mix well.
Pour the mixture into kulfi moulds.
Cover with aluminium foil, then insert ice cream sticks and freeze for 6-8 hours or till it is firm.
To unmould: We can remove the mango kulfi from the moulds by dipping the moulds in water for a few seconds.
Garnish with almond and pistachio slivers and serve immediately.
