Instructions

Preheat oven to 350 degrees F (175 degrees C).

In a large bowl, combine the flour, butter, and water. Mix until the mixture resembles coarse crumbs.

Divide the dough in half and roll out each half into a 12-inch circle. Place one circle in a 9-inch pie plate and pour the rhubarb filling into the crust. Top with the second circle of dough and crimp the edges to seal. Bake in the preheated oven for 40 minutes, or until the crust is golden brown and the filling is bubbly.

Let cool for at least 1 hour before serving.
