How to Make It
Combine pineapple and sugar in a medium saucepan. Bring to a boil over medium, stirring occasionally. Reduce heat to medium-low, and simmer, stirring occasionally, until softened and slightly thickened, about 15 minutes. Remove from heat, and cool slightly, about 10 minutes.
Transfer mixture to a blender. Add coconut cream, zest, and juice; process until smooth. Pour into the bowl of an electric ice cream maker, and freeze according to manufacturer’s instructions, about 1 hour. Serve immediately, or freeze for later use.
