In large saucepan heat juice, water, sugar and cinnamon over medium heat until sugar dissolves, about 5 minutes. Add pears. Cook, turning pears frequently, until tender, about 15 minutes. Using slotted spoon, transfer pears to cutting board. Reserve poaching liquid. Using sharp paring knife, slice each pear into fan shape while still keeping pear and stem intact. Place pears on 4 individual serving plates. Press down gently to fan the pear out. Cook poaching liquid over medium-high heat until slightly thickened and syrupy, about 5 minutes. Remove cinnamon stick. Spoon syrup over pears. Sprinkle with almonds.
