- Select ripe, fragrant peaches that yield slightly to gentle pressure. Bring a large pot of water to boil and prepare an ice bath. Score an "X" at the bottom of each peach, then blanch them in boiling water for 30-45 seconds. Transfer immediately to the ice bath. The skins should now peel away easily. Remove pits and slice peaches. 
- Place peeled and sliced peaches in a blender or food processor along with sugar, lemon juice, honey, and salt. Blend until completely smooth, about 1-2 minutes. If you're using the optional alcohol, add it now and pulse to combine. 
- For extra smoothness, strain the mixture through a fine-mesh sieve to remove any fibrous bits (optional). 
- Pour the mixture into a shallow, freezer-safe container. Cover with a lid or plastic wrap and place in the freezer for 45 minutes. 
- Remove the mixture from the freezer—you'll notice ice crystals forming around the edges. Using a fork or hand mixer, vigorously stir the mixture, breaking up any frozen sections and incorporating them back into the softer center. 
- Return the container to the freezer and repeat the stirring process every 30-45 minutes for about 3-4 more times. Each time, you'll notice the mixture becoming progressively firmer. 
- After your final stir, return the sorbet to the freezer and allow it to freeze completely, about 2 hours or until firm enough to scoop. 
- Allow to soften at room temperature for 5-10 minutes before serving for optimal texture.
