- 3 ripe mangoes
- 1/2 cup sugar
- 1/2 cup water
- 1/3 cup coarsely mashed banana
- 2 tablespoons lime juice
- Preheat oven to 350 degrees F. Place whole mangoes in a shallow baking pan and roast until very soft, 70 to 90 minutes. Refrigerate until cool, about 1 hour.
- Meanwhile, combine sugar and water in a small saucepan. Bring to a boil, stirring to dissolve sugar. Remove from heat and refrigerate until cold, about 1 hour.
- When the mangoes are cool enough to handle, remove skin and coarsely chop pulp, discarding pit. Place the mango pulp and accumulated juices in a food processor. Add banana and lime juice; process until very smooth. Transfer to a large bowl and stir in the sugar syrup. Cover and refrigerate until cold, 40 minutes or overnight.
- Freeze the mixture in an ice cream maker according to manufacturers directions. (Alternatively, freeze the mixture in a shallow metal pan until solid, about 6 hours. Break into chunks and process in a food processor until smooth.) Serve immediately or transfer to a storage container and let harden in the freezer for 1 to 1 1/2 hours. Serve in chilled dishes.
