Creating Old-Fashioned Fresh Strawberry Pie is straightforward if you follow these simple steps:

1. Prepare the Crust: If using a pre-made pie crust, follow the package instructions to pre-bake it. If making your own, roll it out and place it in a 9-inch pie pan. Prick the bottom with a fork and bake at 350°F (175°C) for about 15 minutes or until golden. Allow to cool.

2. Prepare the Filling: In a medium saucepan, combine 1 cup of water, sugar, and cornstarch. Stir well and bring to a boil over medium heat. Cook until the mixture thickens, stirring constantly.

3. Add Flavor: Once thickened, remove from heat and stir in the lemon juice and butter. If using gelatin, sprinkle it in at this stage and mix until fully dissolved.

4. Combine Strawberries: In a large bowl, add the halved strawberries. Pour the thickened mixture over the strawberries and gently toss to coat.

5. Fill the Crust: Pour the strawberry mixture into the cooled pie crust, spreading it evenly.

6. Chill the Pie: Cover the pie with plastic wrap and place it in the refrigerator for at least 2-3 hours to allow it to set.

7. Serve: Once set, slice the pie and serve with a dollop of whipped cream if desired.

These steps will guide you in creating this incredible pie effortlessly.
