Begin by slicing and peeling four ripe yellow peaches, ensuring that they are fully ripe for maximum sweetness. Once peeled, place the peach slices into a food processor.

Next, add caster sugar to the food processor with the peach slices and blend for about 1-2 minutes.

Blend the mixture for about 2-3 minutes, stopping occasionally to scrape down the sides for an even consistency.

Once smooth, gradually incorporate lemon juice to brighten the flavor, starting with one tablespoon and tasting as you go.

Transfer the blended sorbet mixture into an airtight container and freeze for 6-7 hours until firm.

After freezing, let it sit at room temperature for a few minutes to soften slightly for easier scooping.
