If you've got one like this that has metal handles or if you have one that has bakelite handles that are designed for high temperature, and you have to be absolutely sure and don't blame me if you're wrong, then you can season it just like you would season any other piece of cast iron. You put your fat of choice all over the surface of the pan, he didn't until it smokes and pour off the excess. You have to make sure you heat it evenly so that the whole thing is at the same temperature because you want the oil to bond to the surface of the metal and evenly heating it makes sure that it bonds everywhere.

At this point I've given up on my aluminum cookware though and I stick to cookware that I can eat without getting sick. To elaborate on that, aluminum cookware is probably not bad for most people as long as you don't use it for your whole life but it does put aluminum in your food and I'm less able to process heavy metals than others.
