I made the Banana Pudding, and stirred it for over an hour. It wont thicken. So I added a cup of flour after doing some research. Not sure if I did something wrong in making it or the flour was missed in the recipe, but I wasn't bout to let it go out the door. Thickened pretty darn quick after the flour. Needless to say it is great recipe. Really great flavor. Hope this helps someone.
