1 can Eagle Brand milk
1 graham cracker pie crust
Cool Whip topping

Remove the label from the can of milk. Boil the can unopened in a pan of water. Be sure that the water continually covers the top of the can. Cover the pan and allow to boil for 4 hours. After 4 hours remove the can and run it under cold water. Open the can and blend the caramel. Pour into a pie crust and refrigerate. Top with Cool Whip when serving. (It's very rich.)
