There is a slight difference between mango juice and nectar. Pure juice is basically 100% Mango fruit with water. Whereas in mango nectar, fruit is blended using choice of sweetener and water. That said, If you go through most juice recipes with mango on the internet, you will find that they contain all the three ingredients - fruit, sweetener and water! As my recipe for this mango juice is adaptable (with or without sugar), I have taken the liberty to use both the terms here - juice as well the nectar!
