Mango-Lime Ice

Directions

1. 1
   In the bowl of a food processor, combine the mangoes, orange zest, sugar, lime juice, and 1 cup water. Process until the mixture is smooth. Pour through a fine-mesh sieve set over a large bowl then press gently on and discard any solids (there will be about 3 cups syrup). Transfer to a freezer-safe dish, cover with plastic, and freeze until the mixture is firm 2 inches in from the sides, about 2 hours. Scrape into a food processor and process until the mixture is slushy. Repeat the freezing and processing 2 more times, then freeze for at least 1 hour before serving. DO AHEAD:
