Peel the pears without removing the stems and place them in a deep sauce pan. In another sauce pan, bring the merlot, lime juice, brown sugar, zests, vanilla bean, and enough water to cover the pears to a boil. Pour the liquid over the pears and simmer very slowly until just tender (10 to 15 minutes). Remove the pears carefully to a serving dish. Rapidly reduce the remaining liquid by boiling down to about a cup. Pour over pears. Present on a bed of whipping cream sprinkled with cinnamon.
