*Tapioca starch is essential for this recipe. It's what gives the cheese it’s gooey and stretchy texture. Any other starch or flour will not get the same result.
*If you want to return the cold mozzarella back to dipping consistency, reheat over medium heat while stirring constantly so it doesn't burn. Once it is hot and bubbling it might have thickened up too much. You can thin it out by adding a tablespoon of water at a time, stirring it in until desired consistency is reached.
*If you don't have a high-powered blender, you may want to pour the liquid through a fine mesh strainer or cheesecloth before cooking to remove any cashew bits that didn't grind up. This will ensure a smooth cheese texture.
