Peel the pears and remove the seeds. Dice into slices lengthways (approx. 1cm thick)..
Melt the butter in a saucepan alongside the star anise and cloves, until the butter has gone a light-golden colour.
Add the pears to the saucepan and cook until the liquid has absorbed, and the pear is soft. Add the ground nutmeg and set aside to cool.
Preheat the oven to 180°C fan.
Bring the pastry back to room temperature and roll it out with a rolling pin until it’s approx. 3mm thick. Line a non-stick tart mould with the pastry. Cover with a sheet of baking parchment and add ceramic baking beans or uncooked rice. Cook for about 10 minutes, then remove the beans and finish cooking until the dough has turned golden in colour.

Peal the pears leaving the stalks intact. With a small melon baller or a spoon, scoop out the seeds, starting from the bottom of the pear.
In a deep saucepan add the water, sugar and the spices. Bring to the boil and add in the pears.

Twist the scored pears to create a spiral shape and place them on top of the tart.
