Freeze the peaches: Place the peach slices on a tray and freeze for 2–3 hours until solid.

Blend: In a blender or food processor, add frozen peaches, sugar, lemon juice, and water. Blend until smooth.

Adjust: Taste and adjust sweetness or add a splash more water if needed.

Freeze again (optional): For a firmer texture, transfer to a container and freeze for 1–2 more hours.

Serve: Scoop into bowls or cones and enjoy immediately!
