Traditionally panna cottas are served on plates, turned out of ramekin moulds. Personally, I find this process of turning the panna cottas out onto a plate to be entirely unnecessarily, offering very little to the presentation of the dish and no benefit to the taste! Instead, I recommend serving in glasses - you can use small juice glasses, wine glasses or even a nice set of tea cups. Each serving is roughly half a cup but you can make these larger or smaller dependent on the size of serving glasses you have available. I have not tested this recipe unmoulded from a ramekin. While it sets firm enough to hold shape as you use a spoon to eat, it is creamy and may struggle to release from a mould.
