Wash the orange hot, dry and peel half of the peel with a peeler. Halve the orange and squeeze it. Cut the vanilla pod lengthwise and scrape out the pulp. Place the pulp and pod with wine, 300 ml water, sugar, cinnamon, lemon juice, orange juice and zest in a large pot.
Peel the pears and place them in the wine stock. Bring to the boil covered and simmer for 15-20 minutes until the pears are soft. Lift out the pears. Boil down wine stock open for 10-15 minutes until slightly syrupy. Serve hot or cold with the pears.
