The rectangular pizza stone from Napoleon is perfect for grilling and baking. The porous pizza stone absorbs moisture from the pizza crust, pastries, or bread, resulting in crispy and light outcomes. Odors and flavors do not cling to the natural surface. Just like your favorite cast iron skillet, this pizza stone gets better and more effective over time. It is recommended to wash the rectangular pizza stone by hand with warm water once it has completely cooled down. Avoid using too much dish soap and scrubbing.
