Holes in Pizza Crust?

Have you ever seen small holes in pizza crust and wondered why?  Well, wonder no more.  We all know that pizza crust can be somewhat soggy especially if loaded with tons of toppings.  In order to create a crispier crust, small holes are rolled into the raw dough with a dough punch roller.  By doing this to the crust before going in the oven, the holes create more air flow and allow steam to exit the crust.  And, what is the result?  A crispy, less soggy crust with no bubbles.  Interested in a dough punch roller, check it out on Amazon, https://www.amazon.com/SCI-Scandicrafts-Dough-Punch-Roller/dp/B001TJ10GO
