Black absorber coating or paint to absorb heat

I need your help. Not some expensive process. But some type of thing that everyone will be able to copy. I am making a Solar Cooker for food cooking. I need your help as to what is the best "Absorber Material" OR Paint that I can coat the surface with to absorb "more" solar gain. I need your advice, I am building a cheap cooker of cardboard, wood, aluminum. Please respond as soon as possible.

Thanks, it will help.

Hey you might want to use salt rocks, they work great and are inexpensive, if not try to use copper to absorb some heat.
