Place the sugar, cloves, lemon parings, zest and juice, cardamom, cinnamon and star anise in a saucepan. Add the water, stir and bring to the boil. Simmer for 5 minutes and then leave to infuse for a few minutes, while preparing the pears.
Peel the pears from the stalk to the base. Trim off the base so that each pear can stand easily.
Place the peeled pears in the sugar syrup and simmer for 20 minutes or until just tender and starting to become translucent.
Carefully lift the pears out of the syrup and set aside. Boil the syrup for a further 20-25 minutes or until the liquid has reduced right down, is glossy and coats the back of a spoon.
Return the pears to the syrup and carefully turn in the pan to coat and give them a glossy sheen. Lift the pears onto a serving plate. Drizzle with lemon zesty syrup before serving.
