Dice the flesh of the mango and make Puree using a blender keep it aside.

Combine cooled mango and condensed milk in a bowl. Add turmeric Whisk until combined.
Beat cream with a hand held beater or stand mixer until stiff peaks form

Take a scoop of cream and put it in the mango mixture. Fold through until mostly combined - lumps is fine

Pour into a container (preferably with a lid). I recommend glass, if you can, or other non reactive container.
Place a piece of baking / parchment paper on the surface. Then place lid on or using cling wrap.
Freeze for 12+ hours.

Remove parchment paper. Stand for 5 minutes to soften slightly, then scoop and serve!
If frozen for 24 hours or longer, it will need a couple of extra minutes to soften to a scoop able consistency.
