Blend together the mango, Tatua Whipping Cream and sugar, until smooth. Transfer to a large mixing bowl and chill.
Fill a medium-sized saucepan with water and bring to a boil. Rince the sago pearls well with running water and add to the boiling water. Reduce to a simmer and cook for 10-15 minutes, stirring often, until the pearls are translucent.
When cooked, drain the sago pearls and rinse under cold water. Add to the chilled mango mixture and mix well.
Spoon into serving bowls or glasses and garnish with toasted coconut chips and chopped pistachio nuts.
