A recipe for great pizza dough is beyond the scope of this missive. But if you have time and love a great thin crispy crust, try Peter Reinhart’s Napoleon Pizza Dough recipe (a Google search will find it for you.) You can actually freeze the dough balls to use in the future, which makes the time investment worthwhile.
For those of you with less time on your hands, buy a “take-and-bake” pizza and follow the directions, using your GMG grill the same way you would use your oven. But for even better results, buy a pizza stone. Bring it up to temperature for at least 15 minutes before you use it. Be sure to sprinkle it with corn meal so the pizza doesn’t stick. You will be astounded at the impact a pellet grill makes on a pizza.
