In large, heavy saucepan, combine clementine mixture, pears, golden and seeded raisins, sugar, peel, wine, cherries, butter, cinnamon, ginger, nutmeg, allspice and cloves. Bring to simmer over medium heat. Reduce heat to low and simmer, stirring frequently, for 45 minutes or until thickened and caramel brown. Stir in rum. Line 60 tart shells with pastry cut to fit with crinkle-edged cutter.
Fill shells three-quarters full with mincemeat mixture.
If desired, using a smaller crinkle-edged cutter, cut out circles of pastry to fit over mincemeat but not touch edges. Brush top crust with cream or milk.
