Pink grapefruit-Campari granita

For the best results for this refreshing granita recipe, use freshly squeezed grapefruit juice. The flavor will be far superior without the harsh bitterness that store-bought juice sometimes has. Just keep in mind when you're at the grocery store that one large grapefruit yields about 1 cup of juice. The only other ingredients you need is superfine sugar, fresh Campari tomatoes, grated lime zest, and some water. Campari tomatoes aren't the same as grape tomatoes. They're redder and rounder and a bit smaller than a regular tomato, larger than a cherry tomato, and are super-juicy and sweet. We're sure you'll love 'em when you try 'em!
