10 cups peeled watermelon chunks, from about 2 melons
1 cup fresh lime juice
1 cup sugar
8 cups water
Fresh watermelon or lime wedges and/or orange peel twists* (optional)
Add the melon in batches to a food processor or blender and puree until smooth, stopping to scrape down the sides. Add the lime juice and sugar and process again.
Pour the melon mixture into a large serving container. Add the water and desired amount of ice; mix well. Add additional ice as needed. Serve in small cocktail glasses. Garnish, if desired, with watermelon or lime wedges and/or orange peel twists.
