In a bowl, toss the sliced strawberries with the granulated sugar. Let sit for about 15-20 minutes, or until the strawberries have released their juices.
Puree the strawberry mixture in a blender or food processor until smooth. Strain the puree through a fine-mesh sieve to remove seeds, pressing gently. Discard the solids.
In a separate large bowl, whisk together the heavy cream, whole milk, vanilla extract, and lemon juice until well combined.
Add the strawberry puree to the cream mixture and whisk until fully incorporated. Taste and add more sugar if desired. Ensure the mixture is well chilled.
Pour the ice cream mixture into your ice cream maker and churn according to the manufacturer's instructions.
Once churned, transfer the ice cream to an airtight container and freeze for at least 2-4 hours, or until firm.
Notes
Serve immediately or store in the freezer. For best results, let the ice cream soften slightly at room temperature before scooping.
