Rock-candy swizzle sticks are available at www.candywarehouse.com.
Fill a large saucepan or stockpot with 1 inch water. Remove the center stem of a collapsible basket steamer. Place the steamer in the saucepan.
Place pears in a small baking dish. Sprinkle ginger over the cavities of the pears. Set each swizzle stick across two pear halves. Set the baking dish on top of the steamer inside pot. Cover pot, and place over medium-high heat. Bring the water to a boil, and reduce to a simmer. Steam pears, rotating swizzle sticks halfway through steaming, until tender, 20 to 30 minutes depending on the ripeness of the pears. Remove baking dish from steamer. Serve pears drizzled with any juices in the bottom of the baking dish.
