Peel the mangoes and take out the pulp. Pour the pulp in the jar of blender. Add lemon juice, salt, and sugar to this pulp. Initially give pulse, and then blend till you get smooth puree of mango. Add more sugar if puree is not sufficiently sweet.
Pour this puree in a freezer proof bowl. Cover it and keep it in freezer for about an hour.
Take out from freezer, and blend the mixture again. Then keep it in freezer covered once again for about an hour. Blend it again and then keep it back in freezer covered once again. Now allow it to freeze. It might take around six hours.
Take it out from freezer when frozen but still soft, scoop out and serve in ice-cream cups. You can decorate it with mint leaves or mango slices if you want.
Recipe Notes
Preferably take mangoes with less fibres. If there are fibres, then after blending the pulp pass the puree through a strainer to remove andy fibre present.
