Add 1/4 cup mango puree to drink, along with rum. Fill glass with ice. Top off drink with club soda.
Mix drink well, using bar spoon.
Serve immediately, garnished with a sprig of mint and a mango slice, if desired. Enjoy!
One large mango will make about 1/2 to 3/4 cup mango puree, so you'll have enough puree for at least two drinks. To make drinks for a crowd, puree multiple mangos at one time, then store puree in the refrigerator until needed.Feel free to substitute mango nectar for the fresh mango. Just keep in mind that mango nectar not pure mango (usually only 20 to 25%), and that it is sweetened. You may want to reduce the sugar or eliminate it altogether, depending on how sweet you'd prefer your drink.
