Now, let’s dive into the heart of the dish. Follow these steps to create a rhubarb pie that will surely become a family favorite:

1. Preheat your oven to 375°F (190°C). As the oven warms, imagine the comforting heat of Mama Lou’s kitchen enveloping you.
2. In a large saucepan over medium heat, combine the rhubarb, sugar, and water. Stir occasionally until the rhubarb begins to soften, about 5 minutes.
3. Mix the cornstarch with a little water to make a slurry, then add it to the rhubarb mixture. Stir until the mixture thickens, about 2 more minutes.
4. Remove from heat and stir in vanilla extract, cinnamon, salt, and lemon juice. The aroma will remind you of those cozy afternoons baking with Ouma.
5. Roll out the pie crust and place it in a 9-inch pie dish. Pour the rhubarb filling into the crust, spreading it evenly.
6. Top with another layer of pie crust, seal the edges, and cut small slits on top to allow steam to escape.
7. Bake for 40-45 minutes, or until the crust is golden brown. Let it cool slightly before serving, allowing the filling to set.
