In a medium bowl, sprinkle strawberries with sugar and let sit for 10-15 minutes until sugar starts to form a syrup.
Place the strawberries and syrup in a blender or food processor; blend until smooth.
Using a fine mesh strainer, strain strawberry mixture into a large bowl, pressing to extract juice, leaving pulp & seeds behind. Discard pulp.
Add buttermilk, half & half, vanilla extract, lemon juice, and salt to strawberry mixture; whisk together to combine. (If the mixture is not cold, refrigerate for 2-3 hours until chilled. This will speed up the process once added to the ice cream maker.)
Pour the mixture into the canister of an ice cream maker, and use according to manufacturer's directions. (It took approximately 20-25 minutes to get a soft serve consistency in the one I have.)
Serve soft if desired, or scoop into a freezer-safe container and freeze until desired scooping consistency is achieved.
