Best Rhubarb Tart

This is based on a recipe I found at allrecipes.com. It's super simple, yet unbelievably delicious.

• Ready In: 1 hr 10 mins
• Serves: 8

Ingredients

• 4  cups rhubarb, chopped
• 1 1⁄3 cups sugar
• 6  tablespoons flour
• 2  tablespoons butter
• 1  ready-made pie crust

Directions

1. Preheat oven to 450°F.
2. Put bottom pie crust in pie plate, do not trim. Combine sugar and flour. Sprinkle 1/4 mixture over bottom crust. Heap rhubarb over mixture. Sprinkle remaining mixture over rhubarb and dot with small pieces of butter. Fold crust inward. (You could also add a top crust and just make it a pie, but I like a little of the rhubarb to be lightly browned.).
3. Place pie on lowest oven rack. Bake for 15 min., then reduce temperature to 350°F and continue baking for 40-45 minute You may want to rim the crust with foil when you reduce the temperature (easier to do if you pre-make the foil pieces before putting the pie in the first time).
