Notes
Special notes from Your Gluten-Free Companion
The egg is used to bind the mixture together, while the olive oil helps with moisture. To guarantee a firm pizza base, ensure the cassava mixture is not runny. Unlike traditional pizza recipes, there is no need to knead this gluten-free mixture and the base can be as thick or as thin as you desire. For a thicker base, use the full mixture otherwise 2/3 yields a thin crust.
