4CupsRaw RhubarbChopped, (About 1 1/2 Pounds or 6 to 7 Stalks)
1Unbaked Pastry Shell
Crumb Topping:
1/2CupBrown Sugar
3/4CupFlour
1/3CupButter
Instructions
In a small bowl, mix together sugar, egg, 2 tablespoons flour, and vanilla.
Add rhubarb to a medium bowl and pour over egg mixture; stir until well combined.
To make the crumb topping, cream butter and brown sugar in a medium bowl and then cut in flour and work into crumbs.
Add the rhubarb to the unbaked pie crust and cover with crumbs. Bake in hot oven (425 degrees) for 15 minutes, then in slow oven (325 degrees) for approximately 1 hour until filling is thick and bubbly in the center.
Place on a wire rack and cool completely, about 4 hours, before cutting into the pie to prevent it from becoming runny.
Notes
This family recipe has been traditionally made as a "French" pie with a crumb topping; however, it may also be made with a lattice top. If so, make an egg wash of 1 egg beaten with 1 tablespoon milk or water. Brush crust with the egg wash and sprinkle generously with turbinado sugar.
