Notes
If you want a restaurant-like touch in your drink, dip the rim of the glasses in water and then dip in powdered sugar or pink salt.Like to have a variation? Substitute the lime juice with orange juice and add some slices of orange rind to the glass. You can also add some mango cubes to the drink for a nice bite between the sips.If you are using canned mango puree, adjust the amount of sugar accordingly, as the canned puree is very sweet, and you don't want your drink to be extra sweet.
