Lemon Granita

So, this is basically frozen lemonade, or a not-so-sweet version of Italian ice. It's super easy, very refreshing, and a low-cal dessert option. You could easily serve this to guests, and they might even be more impressed with it than if you baked a cake. Just garnish with a sprig of mint.

1 Tbsp lemon zest
5 lemons, juiced
1.5 quarts cold water
1/2 - 3/4 c. agave nectar, depending on how sweet you like it

In a tall pitcher, whisk all ingredients until well combined. Pour into a glass baking dish, cover with plastic wrap, and put in the freezer. Every 1-2 hours, scrape the mixture with a fork to break up ice crystals. If you let it go longer, just let it sit out for a bit before attempting to break it up. Serve frozen.
