A baking stone is a transferable cooking surface used in baking. It is usually made of ceramic or stone, food is placed on the baking stone which is then put inside the oven. Sometimes the stone is heated first and baking stone absorbs more moisture to make the food crispier. Due to its poor heat conducting properties and thermal mass of the baking stone, it doesn¡¯t burn the food frequently as compared to a metal or glass bakeware. Some cooks advice to sprinkle corn flour or corn meal on the baking stone to avoid the crust sticking on the stone or to use a parchment paper on the top of the baking stone.
