Italian Summer with Raspberries

Directions

1. Combine the raspberries and agave nectar in a medium pot. Smash the raspberries with a potato masher or the bottom of a ramekin. Add the lemon zest and juice, water, and Prosecco. Layer the mint leaves and twist them, tearing them a bit, in your fingers and add to the pot along with a pinch of salt. Bring to a boil and reduce to a simmer. Simmer for 3-4 minutes or until the raspberries have completely broken down into a liquid. Remove from the heat and cool to room temperature.
2. Whip a egg white until it multiplies a few times in volume and its peaks hold, but still soft and a little droopy.
3. Strain the cooled raspberry syrup through a chinoise or similar sized mesh strainer to remove all the seeds, the zest and the mint. Add the whipped egg white and completely incorporate with a whisk. It's not necessary to be gentle with folding it in since it's not for a non-chemical leavener. The egg white (along with the Prosecco) is there strictly to give the granita a silky texture and to keep it from freezing too solidly. It does the same thing for sorbets and is especially useful when the recipe doesn't call for alcohol.
4. Pour into a baking pan big enough for the liquid to be 1"-2" deep. Pop it in the freezer for 2 hours. It will be partially frozen at that point, especially around the edges. With a spoon, mix the frozen part with the non-frozen part for a homogenous semi-liquid granita. Put back in the freezer for another 2 - 3 hours, checking every hour.
5. Before serving, place the bowls you will use for it in the freezer for at least 30 minutes. Scoop the Raspberry Italian Ice into the bowls using a spoon or ice cream scooper.
6. Eat, relax, savor.
7. Note: This has a much "creamier" texture than a granita, so using a fork to break it up won't have the same result. But It will still have more of the crunchiness of a granita vs the smoothness of a sorbet.
