Step 1Place zest, orange and lemon juices, sugar, cranberries, cinnamon stick and cloves in 3-quart saucepan. Bring to boil and boil, uncovered, until syrupy, about 9 minutes.
Step 2Add pears, gently pressing into syrup. Simmer, covered, until just tender but not mushy, about 3 to 5 minutes; it may take longer if pears are very hard. Cool at room temperature. (Can be made a few days ahead and refrigerated, covered airtight.)
Step 3To serve, remove cloves and cinnamon stick. Serve chilled or at room temperature in small bowls.
