Cut the mango flesh into smaller chunks and put them into a blender.
Blend into a smooth and fine puree with a little bit of water.
Add the evaporated milk to mango puree and give a quick burst in the blender.
Sieve the mango/milk puree through a fine strainer to remove any fiber from the mango.
Add gelatin powder into a pot of cold water to prevent any lumps from forming and mix well.
Add in the sugar and heat gently while stirring continuously until sugar and gelatin are fully dissolved. Do not let the mixture boil.
Set aside to cool down.
Add the sieved mango puree into the gelatin mixture.
Mix thoroughly until fully combined.
