This peach sorbet recipe uses five ingredients and about twenty five minutes of hands-on work to turn ripe yellow peaches into a smooth, scoopable dessert. The base is a classic cooked sugar syrup blended with fresh peach puree and a splash of lemon juice, the same method you'll find behind most restaurant-style fruit sorbets.
Combine the sugar and water in a medium saucepan over medium heat. Stir occasionally until the sugar fully dissolves and the liquid turns clear, about 3 to 4 minutes. Remove from heat and let cool to room temperature, about 15 minutes.
Bring a pot of water to a boil and prepare an ice water bath. Score a small X on the bottom of each peach, then blanch for 20 to 30 seconds. Transfer to the ice water for one minute, then peel, halve, pit, and roughly chop the flesh.
Add the chopped peaches, lemon juice, and salt to a food processor or blender. Blend on high for 1 to 2 minutes, scraping down the sides once, until completely smooth.
Pour the puree through a fine-mesh strainer set over a large bowl, pressing with a spatula to push through as much liquid as possible. Discard the solids. Stir the cooled syrup into the strained puree until combined.
Cover the bowl and refrigerate the mixture for at least 2 hours, or until fully cold. A warm base will not churn properly.
Pour the chilled mixture into the bowl of your ice cream maker. Churn according to the manufacturer's instructions, usually 20 to 25 minutes, until it looks like soft-serve and has visibly thickened.
Transfer the churned sorbet into a loaf pan or freezer-safe container, smoothing the top. Press a piece of parchment paper directly onto the surface before sealing the lid, then freeze for at least 3 hours until firm enough to scoop.
Notes
Use peaches that give slightly under gentle pressure. Underripe peaches taste flat and starchy once frozen.
Don't skip the straining step. Skipping it leaves the sorbet with a stringy texture.
Chill the base fully before churning. A warm base churns into a looser, slushier sorbet.
Add lemon juice gradually and taste as you go. Riper peaches sometimes need slightly more acid to balance the flavor.
Let the sorbet sit at room temperature for 5 minutes before scooping for the best texture.
Freeze the ice cream maker bowl for a full 24 hours ahead of time. A partially frozen bowl won't thicken the sorbet properly.
Store in an airtight, freezer-safe container with a layer of parchment pressed directly onto the surface. Keep it in the back of the freezer away from the door.
Sorbet keeps well for up to 2 weeks before ice crystals start to affect the texture.
Avoid refreezing sorbet that has fully melted, as the texture won't return to smooth once it re-sets.
For a no-churn version, freeze the strained base in ice cube trays, then blend the frozen cubes in a food processor until smooth and re-freeze for an hour.
