Icy melon milk granita is an easy make-ahead treat for a hot summer day. (No need to scrape our sherbet-like mixture every 30 minutes, as with most granitas -- just rake it once at the end for the right consistency.)
Even desserts might be helpful in the battle against disease. Tangy mango granita is packed with flavor and vitamins A and C. Fresh mangoes are loaded with vitamins A and C. Whisking the granita as it freezes ensures that it reaches the proper consistency.
Keep extra clementines on hand in case some of the skins tear and for juicing. If you don't feel like juicing enough clementines to yield 2 cups, use store-bought orange juice to make up the difference.
