Plum Fool

Set aside a few plum slices for garnish. Combine the remaining plum slices, 1/4 cup sugar (or Splenda), ginger and cinnamon in a small heavy saucepan. Bring to a simmer, stirring, over medium heat. Cook until the mixture has softened into a chunky puree, 15 to 20 minutes. Taste and add more sugar (or Splenda), if desired. Transfer to a bowl and chill until cool, about 1 hour.

Meanwhile, set a fine-mesh stainless-steel sieve over a bowl. Spoon in yogurt and let drain in the refrigerator until reduced to 1 cup, about 1 hour.

Whip cream to soft peaks in a chilled bowl. Gently fold in the drained yogurt with a rubber spatula. Fold this mixture into the fruit puree, leaving distinct swirls. Spoon into 6 dessert dishes and cover with plastic wrap. Refrigerate for at least 1 hour or up to 2 days. Garnish with the reserved plum slices before serving.
