Honeydew granita spritzer

Seltzer enlivens this effervescent drink, which consists of sweet honeydew melon puree and mouth-puckering lime juice. 6 cups cubed honeydew melon (about half of a medium melon) 1/3 cup sugar 1/4 cup fresh lime juice Lime peels, for garnish
Instructions:
- Working in batches, puree the melon in a blender. Pour the puree through a fine sieve into an 8-inch square nonreactive dish.
- Put sugar and 1/2 cup water into a small saucepan. Bring to a boil over medium-high heat, stirring until sugar has dissolved. Stir into melon puree. Add lime juice; stir to combine. Freeze, covered with plastic wrap, at least 6 hours (or up to 3 days).
- Scrape granita with a fork; spoon about 1 cup granita into each of 6 glasses. Pour 1/2 cup seltzer into each glass; garnish with lime peels.
