This is a favorite drink of mine. I don't like it strong so I go light on the rum. Add as much as you like.

First I make a simple syrup by bring the water and sugar to a boil and let it cool.

Crush the mint in your hands and add to a gallon pitcher. Add the club soda, simple syrup (water/sugar), lime juice and rum and mix.

Server over ice or add ice to the pitcher being careful to not water down the mojito.
