This simply elegant ice, a mix of peach nectar and Prosecco, has been made famous at Harry's Bar in Venice. Serve it in flutes and top with Prosecco for a lovely aperitif. It is also good on its own, especially between courses. From the May 2005 issue of Bon Appétit. The 'cooking time' is, of course, the 'freezing time'. It takes no more than 10 minutes to make! I've made this with mangoes and it is a recipe that you can certainly have fun with, making with your favourite fruits.
