Eating a whole pie can be hard if you have just finished a meal. Next, it is helpful to like the pie you are going to eat. The cream types are a good choice. They slide down the throat more easily. Placing your hands in the right position adds to the chances of winning. There is a temptation to reach out and help the eating process. This will result in becoming disqualified. Don’t just sit on your hands. If your hands are tied behind your back, you will not be tempted to make use of them.
