Remove the stems from the strawberries and freeze them if they are not already frozen.

Combine all ingredients (strawberries, sugar, lemon juice or zest, and optional salt) in a high-speed blender and blend until smooth and creamy.

If using a regular blender, allow the frozen berries to thaw slightly, then blend until combined.

Transfer the mixture to an ice cream machine and churn according to the manufacturer’s instructions.

Serve immediately for a softer texture or transfer to a container and freeze for 1-2 hours for a firmer consistency.

Store leftovers in an airtight container in the freezer.
