• Prepare the fruit: Cut the watermelon into chunks, removing the rind and seeds. Slice the peaches, removing the pits. Peeling the peaches is optional.
• Blend everything: Add the watermelon, peaches, sugar, lemon juice, and water to a blender. Blend until completely smooth.
• Taste & adjust: Taste the mixture and adjust the sweetness if needed, adding a little more sugar, honey, or sweetener to your liking.
• Strain (optional): For a smoother texture, pour the blended mixture through a fine mesh sieve to remove any pulp.
• Freeze:

  If using an ice cream maker: churn according to your machine’s instructions until it reaches a sorbet consistency.

  If using a freezer: pour the mixture into a shallow container and freeze. Stir every 30–45 minutes for the first 2–3 hours to break up ice crystals, until smooth and scoopable.
• Serve: Scoop into bowls or glasses. Decorate with fresh mint leaves just before serving.

Optional adult version

• Add a splash (about 1–2 tbsp) of peach liqueur, white rum, or ouzo to the mix before freezing for a grown-up twist.
