To prepare the poaching liquid in a medium saucepan combine the water, honey, cinnamon, anise, cardamon, lemon juice, vanilla seeds (removed from the pod), and the empty pod. Then bring the mixture to the boil.
Peel the pears and cut them in half. Gently remove the cores.
Place the prepared pears in the hot poaching liquid and simmer over a low heat for 15-20 minutes or until soft. Check them regularly to make sure they aren't overcooked. Once soft, remove the pears from the poaching liquid and set aside.
To reduce your poaching liquid boil it over a medium heat for about 10-15 minutes. This will intensify the flavour and thicken it slightly.
For the cream, whip the mascarpone with the maple syrup just until combined.
For the crumble topping, preheat the oven to 180°C. Combine all the ingredients until the mixture form crumbs and bake them on a baking tray lined with baking paper for about 10-12 min.
Serve your pears with the mascarpone cream, baked crumble, and reduced poaching liquid.
