Berries: Rinse, stem and halve large strawberries. Peel the stone fruits, halve, pit, and chop larger specimens into 1/2-inch pieces.
Puree the fruit in a food processor along with the sugar, lemon juice, vodka and salt. Pour into another vessel and refrigerate until the mixture reaches at least 40 degrees F, 4 to 6 hours.
Churn in an ice cream machine according to the manufacturer's instructions until the mixture resembles soft serve ice cream. Freeze for at least 4 hours in an airtight container or until ready to serve
