Preheat oven to 300°. Prepare double crust pie dough. Line bottom crust. Mix together all ingredients except butter. Pour in prepared pie shell. Dot with butter. Top with top crust. Cut slits for steam. Bake 35-40 minutes until browned and bubbly.
Notes
This was the pie Joey and I made when I taught him how to make Rhubarb pie. The lattice top was his idea. It tasted great!!
