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 pears occasionally, until tender but still holding shape.
03 - Remove pears with a slotted spoon and set aside. Increase heat and reduce poaching liquid for 5 minutes until slightly thickened.
04 - Arrange pears on serving plates, drizzle with the reduced syrup, and sprinkle with crystallized ginger and fresh mint, if desired. Serve warm or chilled.
