The key to this dessert is to use real vanilla, either a vanilla bean or vanilla bean paste which are both readily available in supermarkets; please don’t settle for essence or even extract for this one
*Tip: Wash and dry the vanilla pod after making the panna cotta. Cut into 4 pieces and place in a jar with a couple of cups sugar and seal. After a week or so you will vanilla scented sugar to add to coffee, sprinkle over a tea cake or whatever else comes to your imagination.
