Prepare the Fruit: If you're using fresh fruit, wash it thoroughly and cut it into smaller pieces. If using frozen fruit, let it thaw for a few minutes.
Blend the Ingredients: Place the fruit, sugar, lemon juice, milk, cream, and corn syrup (if using) into a blender. Blend until smooth and creamy.
Add Flavorings: Stir in the vanilla extract, mint leaves (if using), and alcohol (optional).
Freeze: Pour the mixture into a shallow, freezer-safe container. Cover and place it in the freezer.
Stir Regularly: After 30 minutes, use a fork to scrape and stir the mixture every 30 minutes for the next 2-3 hours. This helps break up any ice crystals and ensures a smooth texture.
Serve: Once the sherbet is fully frozen and smooth, scoop into bowls or cones and serve!
