1 c Ripe plums; peeled, chopped 1/4 c Sugar Sweet cream Base If you really like plums, this is the flavor to try. The recipe works well with any variety of plum, as long as it's fresh ( and ripe!) Combine the plums and sugar in a bowl and mash until pureed. Cover and refrigerate 1 hour. Prepare the sweet Cream Base. Drain the juice from the plums into the cream base and blend. Return the plum puree to the refrigerator. Transfer the mixture to an ice cream maker and freeze following manufacturer's instructions. After the ice cream stiffens ( about 2 minutes before it is done) add the plum puree, then continue freezing until the ice cream is ready. Makes 1 generous quart.
