Rinse orange hot, rub dry and cut into slices. Bring 400 ml water, white wine, cinnamon, 125 g sugar and orange to the boil in a pot. Peel pears and cut off about 1/4 of the stem end.
Remove the core housing with a ball cutter. Poach the pears in the wine stock for about 15 minutes.
Caramelise 50 sugars in a pan, stir in the hazelnuts. Put them on a piece of aluminium foil coated with oil, let them cool down a bit and chop them roughly. Mix cranberries and nuts. Remove pears from the liquid, drain and fill with the nut-cranberry mixture.
Dust with cocoa powder.
