Cut the vanilla pod lengthwise and scrape the pulp into a small pot. Add the vanilla pod, cinnamon stick, sugar and 150 ml water. Bring everything to the boil and boil down over a high heat for 6-8 minutes until syrupy. Then let it cool down
Meanwhile peel the mangos and cut the flesh from the stone. Weigh 250 g fruit flesh, mix with the lime juice and puree. Cut the rest of the fruit flesh into slices for decoration, cover and put in a cool place. Sieve the sugar syrup and stir it gradually into the puree.
Pour the mango puree into a metal or plastic bowl and freeze in the freezer for at least 5 hours. Stir every 30 minutes.
Pre-cool glasses. Inject or fill sorbet into the glasses. Decorate with mango wedges and possibly lemon balm. Wafer rolls go well with it
