01 - Combine the grape juice, sugar, cinnamon stick, star anise, and lemon zest in a large saucepan. Bring to a gentle simmer over medium heat, stirring continuously until the sugar completely dissolves.
02 - Carefully add the pear halves to the simmering syrup, ensuring they are mostly submerged in the liquid.
03 - Maintain a gentle simmer for 20 to 25 minutes, turning the pears occasionally to ensure even cooking, until they are tender but still hold their shape.
04 - Remove the pears using a slotted spoon and set aside. Increase the heat to medium-high and boil the syrup for 5 to 10 minutes until it thickens slightly.
05 - Discard the cinnamon stick, star anise, and lemon zest. Return the pears to the reduced syrup and allow to cool to room temperature, or refrigerate until chilled.
06 - Plate the pears drizzled with the aromatic syrup. Garnish with fresh mint leaves and crushed nuts if desired.
