Poach the pears:
In a large saucepan, combine the pears, wine, sugar, cloves, star anise, cardamom, and cinnamon and poach for 30 minutes over low heat
Take the pears out of the liquid and set aside to cool
Add 500ml water to the poaching liquid and boil to reduce the liquid by half. Set aside and let cool
Make the cake:
Preheat the oven to 170°C
Grease 1.5l loaf pan and line it with baking paper and grease the baking paper
Beat the butter and sugar in a large bowl until creamy
Beat in the eggs one at the time and beat well after each addition
Add the vanilla extract and beat well
Sift the flour and salt over the batter and fold it in
Spoon the batter into the pan
Press the pears in, stem end up
Bake for 40 minutes, until a toothpick inserted into the cake part comes out clean
Allow to cool in the pan, then gently remove the cake from the pan to a rack to cool completely
Before serving, set a heatproof bowl over a pan of simmering water, making sure the bowl doesn’t touch the water
Stir the chocolate in the bowl until melted
Using a spoon, drizzle the chocolate over the cake and create nice stripes on top
Let the chocolate dry for a bit and serve the cake in thick slices, with the reduced pear syrup poured on top
