1 1/3 pounds peeled fresh pineapple chunks
2 tablespoons packed dark brown sugar
2 cups of diced fresh pineapple
1 cup lightly packed mint leaves, plus for garnish
2 cups of your favorite silver or white rum
3/4 cup fresh lime juice
1 1/4 cups chilled club soda
Lime wedges, for garnish
In a saucepan, bring the pineapple, brown sugar and 4 cups of water to a boil.
Simmer over moderately low heat, stirring, until the pineapple is very soft and the mixture is reduced about 40 minutes.
Strain the mixture into a bowl, squeezing as much juice out of the pineapple, then discarding the fruit.
Let the syrup cool, you should have about 1 1/3 cups.
In a pitcher place the pineapple and mint leaves and mash around a bit.
Stir in the rum, lime juice and 1 cup of the pineapple syrup.
Pour into 8 glasses and add ice. Top with club soda and garnish with mint sprigs and lime wedges.
