This is the very basic way to make mango punch, just two ingredients, mangoes, and water.
If the mangoes are very sweet just add water to dilute the sweetness, if they are not too sweet then add sugar to tatse, you can also add ice to make a great smoothie.
If the mangoes are acid then add some lemon juice to taste to remove the acid taste.
Remove the peels, then cut the mango flesh into pieces. Remove the seed at the same time.
Place the ingredients in a blender; process until smooth.
