PYRAMID DESIGN - It keeps the food elevated to allow the hot air to pass underneath. This allows the bottom to cook but not burn as normally happens with flat pans. It helps remove the grease and allows for foods to be crispier.
EASY TO CLEAN -- use a toothbrush to get in the valleys.It makes cleanning pretty easy that way.Worse case if is a bit caked on, soak it in hot water and Oxy clean for a few minutes and everything fall right off.
Do not put it directly on fire.
