01 - In a large saucepan, combine grape juice, sugar, cinnamon stick, lemon zest, and vanilla extract. Bring to a gentle simmer over medium heat, stirring until sugar dissolves completely.
02 - Add pear halves to the simmering liquid. Reduce heat to low, cover, and poach for 20-25 minutes, turning occasionally until tender but not falling apart.
03 - Using a slotted spoon, carefully transfer the pears to a serving dish, leaving the poaching liquid in the pan.
04 - Increase heat and simmer the poaching liquid uncovered for 5-7 minutes until slightly reduced and syrupy in consistency.
05 - Pour warm syrup over the pears. Let cool to room temperature or chill in refrigerator before serving.
06 - Serve pears with grape syrup drizzled over the top. Garnish with fresh mint, whipped cream, or vanilla ice cream if desired.
