01 - In a medium saucepan, combine water, sugar, sliced ginger, lemon zest, and lemon juice. Bring to a simmer over medium heat, stirring until sugar dissolves.
02 - Add pear halves to the poaching liquid ensuring they are mostly submerged. Cover and simmer gently for 20 to 25 minutes, turning occasionally until tender but still intact.
03 - Remove pears with a slotted spoon and set aside. Increase heat and reduce the poaching liquid for 5 minutes until slightly thickened.
04 - Arrange pears on serving plates, drizzle with reduced syrup, and sprinkle with crystallized ginger and fresh mint if desired. Serve warm or chilled.
