The lemon granita from Valentine's Day was so delicious, that I made another one on a whim, but this time used red ruby grapefruit juice. The juice was so tart that is made a very delicious granita! Even better than the lemon. The color was exquisite. It was even better than the lemon granita. The girls and I have been trying to come up with alternate flavors that would be delicious and I thought about cantaloupe and Al suggested watermelon. The acidic flavor of the lemon and grapefruit made it especially sweet-tart, so I am curious how the melon flavors would be.
