In a medium sized saucepan, combine the 1 Tablespoon cornstarch with the 1/2 cup granulated sugar and 1/4 teaspoon salt. Slowly whisk in the 1 cup milk.
Whisking constantly, heat the mixture until bubbles begin to form around the edges, around 180℉. Once it reaches 180℉, remove from heat and allow to cool to room temperature.
Pour the milk mixture into a medium to large bowl with a lid. Whisk in the 2 cups heavy whipping cream and 1 1/2 cups strawberries, pureed . Chill the entire mixture overnight or 12-24 hours.
Churn in an ice cream maker; follow the manufacturer's instructions on the ice cream maker for directions. Once churned, freeze ice cream in an airtight container.

Fresh strawberries work best for the best taste, however you can substitute frozen strawberries; thaw completely before using
