You don't even need an ice cream maker for this. Just buy some peaches and this sorbet will practically make itself. (Ok, it won't, but you can make it happen with minimal work on your part).
Here's what you do--
You'll need: an 8 x 8 baking pan (feel free to substitute a pan of comparable size)
Ingredients: 5 peaches, peeled, pitted and roughly diced
juice of one lemon
1 cup sugar
1/2 cup water
1 Tablespoon fruity liqueur (optional, it helps the sorbet to freeze smoothly)
Blend all of the ingredients until smooth. Pour this peachy sweet nectar of the gods into your baking pan. Freeze uncovered. After an hour, remove it from the freezer and whisk the liquid around. This adds air to the mixture, so that you'll get a light sorbet instead of a giant peach popsicle. Repeat the whisking 2 or 3 more times, freezing an hour between each time. Allow it to freeze at least an hour or two more with no whisking.
Remove the pan from the freezer about 15 minutes before you want to eat it and let it soften a bit. Scoop and eat! Delightful, no?
