How to Make It
In a small saucepan, combine the sugar and water and bring to a simmer, stirring to dissolve the sugar. Pour the syrup into a bowl and let cool. Add the pears and lemon juice to the syrup and toss well.
Transfer the pears and syrup to a food processor and add the Riesling. Process to a smooth puree. Pour the puree into six 1/3-cup popsicle molds and freeze until hard, at least 1 hour.
