You need: 3 cups hung curd, 12 tsps sugar, 1 tsp rose water, 2 pods crushed cardamom, pulp of 2 mangoes (i used the rasaal mango that you get very easily in hyderabad)
To make: Whip everything . Garnish with crushed pistachios. Chill and serve. You can reduce / increase the quantity of sugar on the basis of the sweetness of the mangoes.
Enjoy your amrakhand, if you do decide to make it (trust me, it's super easy to make and super-duper-tasty to eat and it would be crazy to not try it.)! Do share a picture :)
