Begin by washing your peaches thoroughly, ensuring they are clean and free from any dirt. If using fresh peaches, peel them to enhance the texture. Cut into slices and set aside. For frozen peaches, allow them to thaw slightly for about 10-15 minutes.

In a blender, combine the sliced peaches, sugar, cold water, and lemon juice. Blend on high speed until smooth and creamy, about 1-2 minutes.

Pour the smooth mixture into a freezer-safe container. Use a spatula to scrape down the sides and ensure all the mixture is included. Cover with a lid or plastic wrap.

Place the container in the freezer and let the sorbet freeze for at least 4 hours until firm. Give it a gentle stir halfway through if desired.

When ready, remove from the freezer and let it thaw for about 5 minutes at room temperature before scooping.
