Preheat oven to 200C. Simmer honey, juices, rinds, and vanilla bean and seeds in a small saucepan over medium heat until reduced to a light syrup (8-10 minutes). Place pears, cut-side up in a roasting pan large enough to fit pears snugly. Pour over honey mixture and roast, basting occasionally, until tender and beginning to caramelise (20-25 minutes). Remove pears from pan, stir through orange-blossom water and serve pears and syrup with yoghurt and pistachios.
