12 very ripe kiwifruit, peeled and diced
Juice of 2 limes
1/2 cup superfine sugar
11/4 cups water
6 ounces rum
4 unpeeled kiwifruit slices for garnish
Put kiwifruit in a food processor with lime juice. Pulse only a few times until fruit is just pureed. Mix sugar and water and combine with puree, pulsing a few times until smooth. Put kiwifruit mixture in a metal or glass pan and mix with a whisk or wooden spoon. Freeze until solid. Scoop up frozen mixture and put into a food processor or blender. Add the rum and puree just until a slushy drink is formed. Pour into goblets. Make a slit halfway into the kiwifruit slices and put a slice on the rim of each glass.
By switching the rum to tequila and adding a little Triple Sec this drink becomes a margarita.
