6 1/2 limes
2/3 C sugar, or to taste
1/2 C coarsely chopped peppermint
2 C white rum
4 C club soda
8 sugarcane swizzle sticks for garnish, optional

Cut the limes into quarters and add them to a pitcher along with the sugar. Mash the limes and sugar together using a muddler or the back of a wooden spoon until the juices from the limes have been released and the sugar has mostly dissolved into the lime juice. Add the mint to the pitcher and mash it together with the lime-sugar mixture. Pour the rum and the club soda into the pitcher and stir together. Put two pieces of the quartered limes in each tall glass and add ice cubes. Pour the mojito over the ice and garnish with a sugarcane swizzle stick, if desired, and serve immediately.
