Grapefruit Granita
Fresh citrus juice is ideal for making granita; it is easy to extract and it freezes particularly well. For variety, use an equal amount of any type of citrus juice in place of grapefruit. Campari lends a pleasant bitterness and dash of color to grapefruit granita; add 3 tablespoons to the proportions below. To make apple granita, puree four peeled and cored apples in a food processor with 1/2 cup water and the juice of one lemon (to preserve the color); strain, and you should have 2 cups juice. For watermelon granita, puree about 3 cups cubed melon in a processor; strain.
