When I say "panna cotta" most of the time the answer here in Uk will be "what?".
Panna cotta it's one of the classic Italian dessert that you have to try at least once in your life. Milk, double cream and gelatin are the main ingredients, add your favorite flavors and your fantasy and voila' panna cotta will be in your fridge.
For this recipe I used blueberry yogurt as well to give an intense berry flavor and elderflower cordial (one of my favorite English thing!).
