This drink can be made ahead of time and stored in a cooler or in the freezer of your RV until happy hour. We like to tie up the mint in a cheesecloth before putting in in the ziplock to keep bits of mint from floating around in your drink and ending up in your straw.
1 cup mint leaf
1 (12 ounce) can limeade
3 cups water
1/2 cup sugar
12 ounces bacardi rum
Place sugar and 1 cup water in saucepan, bring to a boil and stir until sugar is dissolved. Remove from heat and cool.
Place mint leaves in a bowl with the juice of 1 lime and add a sprinkling of sugar. Using a muddler or the end of a wooden spoon or rolling pin, mash the mint leaves .
Combine the sugar syrup, limeade, remaining water, mashed mint leaves/lime juice mixture, the juice form the other lime and the rum in large bowl. Cut up the limes and add to the mixture.
Pour the mixture into a resealable gallon size freezer bag and allow to freeze.
When ready to serve use a ratio of 1:1 of slush and club soda.
