Aluminium pans do not need to be seasoned as they will not rust. However it is generally considered wise to oil pans as this helps to create a non-stick finish as well as darkening the pan. Aluminium pans are available in base diameters of 6" to 16". They work well in deck ovens. The round rim adds strength and eliminates sharp edges. Ideal for proofing dough. Easily removed from oven with an oven mitt.
