*If you don't have macarpone, substitute two 8-ounce packages cream cheese, softened, for the mascarpone cheese and 3-ounce package of cream cheese.
Halve kumquats, removing any seeds with a knife point. In a small saucepan stir together 1/2 cup sugar and 1/2 cup water. Heat to simmering, stirring to dissolve sugar. Add kumquats. Cook about 10 minutes or until syrup thickens and kumquats soften. Remove from syrup, allowing excess to drip off, and cool on a baking sheet lined with parchment paper.
