Pre-bake your pie crust according to the instructions on the packaging, or use a homemade crust recipe. Allow the crust to cool completely before assembling the pie. This can be done ahead of time and refrigerated.
In a medium-sized saucepan set over medium-high heat, stir together the water, granulated sugar, salt, lemon juice, vanilla extract, and cornstarch. Whisk the mixture continuously for about 3 to 5 minutes, or until it becomes thickened and glossy.
Once the glaze has thickened, take the pan off the heat and immediately whisk in the strawberry gelatin powder until it dissolves entirely and the mixture is smooth.
Transfer the fresh, prepared strawberries into a large mixing bowl. Gently fold the warm gelatin glaze into the strawberries, ensuring the fruit is thoroughly coated.
Spoon the glazed berry mixture into the cooled pie crust, spreading it evenly to the edges.
Place the filled pie into the refrigerator and chill for a minimum of 3 hours, or until the glaze is fully set and firm to the touch.
Slice into portions and serve topped with a generous amount of whipped cream to capture the nostalgic charm of the original.
