In a small bowl, combine custard powder with ¼cup of milk. Whisk well and set aside.
Combine rest of the milk and sugar in a medium size saucepan. Bring to a boil on medium heat.
Once the milk comes to a boil, remove from heat and slowly add the custard powder mixture whisking continuously.
Place the pan back on medium heat. While whisking continuously, bring the mixture to a simmer and cook until the mixture thickens and coats the back of a spoon. This takes about 4~5 minutes.
Stir in the mango puree and ground cardamom, mix well and cook till mango puree is heated through, about 2~3 minutes.
Remove from heat and let the mixture cool completely. Place a plastic wrap on the top of the custard to prevent skin to form. Chill in the refrigerator for at least 4 hours or overnight before serving.
Remove from the fridge and whisk the custard to make it creamy. Divide between serving bowls and serve immediately topped with fruit. Enjoy!!
