Fold in rhubarb. Pour into pie shell; cover top of pie with remaining pie shell. Crimp edges together and cut slits in top shell.
4Bake in a preheated 450 degrees F (230 degrees C) oven for 15 minutes. Reduce oven temperature to 350 degrees F (175 degrees C).Continue baking the pie at this temperature for 35 more minutes.
