Cornmeal is often used for pizza dusting to prevent the dough from sticking to the pizza peel or baking surface. It creates a barrier between the crust and the stone, making it easier to slide the pizza on and off. Additionally, cornmeal adds a slightly nutty flavor and a crunchy texture to the crust, enhancing the overall taste1. However, some experts suggest that cornmeal isn't necessary if the pizza stone is properly preheated, as a hot stone naturally prevents sticking. If you do choose to use cornmeal, a medium-coarse grind is recommended to balance texture without making the crust too gritty2.
