For best results, use ripe, in-season fruit to maximize natural sweetness and flavor intensity.
If you do not have an ice cream maker, you can freeze the mixture in a shallow container, stirring vigorously every 30 minutes during the first few hours to prevent large ice crystals from forming.
To prevent the fruit from sinking, you can toss the chopped fruit with a tablespoon of sugar or corn syrup before folding it in.
Store leftovers in an airtight container in the freezer for up to two weeks. Let sit at room temperature for 5 minutes before scooping for easier serving.
