Heat a small pan with about 50 ml water. Add 2 tsp of vegetarian gelatine to it. Mix gently. Set aside for about 10 minutes and it becomes a thick mixture.
I did this by following the instructions that came with the gelatine.
Rinse to clean your mango under running water and keep it aside.
Peel the skin and cut the mango roughly to small pieces.
Reserve about 2 tbsp of the chopped mango and the blend the rest.
The mango puree will come to about 3/4 cup approximately.
Add all the chopped mango pieces, sugar, coconut milk and blitz to a smooth puree using a blender or mixer.
Add double cream and blitz for a few seconds to blend it with the mango puree.
Strain the mango mixture for a smooth texture in a wide bowl.
Do not waste any bits of the mango mixture. I cleaned every little left in the blender with about 50 ml of warm water, poured it in a bowl and kept aside. I am going to optionally use it for the gelatine.
