Begin by gathering your ingredients: fresh or frozen peach slices, granulated sugar, cold water, and lemon juice. If using fresh peaches, wash them thoroughly and peel before slicing. Measure out all ingredients for easy access as you proceed.

In a powerful blender or food processor, combine your peach slices, sugar, cold water, and lemon juice. Blend on high speed for 1-2 minutes until the mixture is completely smooth and creamy.

Pour the blended peach mixture into a metal loaf pan or any freezer-safe container you have on hand. Cover tightly with parchment paper or aluminum foil if the container doesn't have a lid.

Place the container in the freezer and allow the sorbet to freeze for at least 4 hours, or until it becomes solid.

Before serving your delightful peach sorbet, remove it from the freezer and let it sit at room temperature for about 5 minutes to soften slightly.

Using an ice cream scoop, serve generous portions of the peach sorbet in chilled bowls, garnishing with mint leaves or a slice of peach.
