Add the sliced peaches, honey, and lemon juice into a blender. Start blending on low speed, then gradually increase to high, until the mixture is smooth and creamy, with no chunks remaining.
Stop the blender and check the texture; it should be thick and slushy. If the mixture is too firm, add a splash of water or extra lemon juice and blend briefly to loosen it.
Pour the blended mixture into a shallow container or freezer-safe dish. Smooth the surface with a spatula to ensure even freezing.
Place the container in the freezer and let it chill for at least 4 hours or until fully frozen. Stir the mixture every 30 minutes during the first 2 hours to prevent large ice crystals from forming.
Once frozen, remove the mixture from the freezer and let it sit at room temperature for a few minutes to soften slightly. Then, scoop into bowls or cups.
Serve immediately and enjoy this icy, fruit-forward treat, with a vibrant color and smooth, scoopable texture.
