5 cups fresh or frozen unsweetened strawberries, thawed
2/3 cup sugar
2/3 cup water
1/4 cup lemon juice
Place the strawberries in a blender or food processor; cover and process until smooth. In a saucepan, bring sugar and water to a boil. Cook and stir until sugar is dissolved, about 5 minutes; cool slightly. Add to blender. Add lemon juice; cover and process until combined.
Pour into a shallow freezer container; cover and freeze for 4-6 hours or until almost frozen. Just before serving, whip mixture in a blender or food processor.
