Remove the stems from the strawberries.
Place the strawberries into a blender or food processor and blend until completely smooth. You should have about 1 quart of strawberry purée.
Add the sugar and blend for about 30 seconds until dissolved.
Add the lemon juice and kosher salt, then blend again until fully combined.
Taste the mixture and adjust the lemon juice or salt if desired.
Strain the purée through a fine-mesh sieve for an extra smooth texture.
Transfer the mixture to the refrigerator and chill for 2 to 3 hours until thoroughly cold.
Pour the chilled mixture into an ice cream maker and churn according to the manufacturer's instructions. This Strawberry Sorbet develops its smooth, refreshing texture during the churning process.
Transfer the sorbet to an airtight container and freeze for another 2 to 3 hours before serving.
