I was faced with that dilemma of having to use a 10" skillet to bake a potato dish that required top heat. The problem is that the lid of the skillet is domed, so you can't get too many coals on top. I recalled a past discussion about creating a "dam" out of aluminum foil that would ring the lid and hold the coals in place. So I figured I'd try that method.
But my good friend Ken had another idea. As we were preparing to start cooking, he said he'd be back in a few minutes and ran off. Just about the time I needed to start cooking with the skillet, he returned with his solution to the lid problem. I must admit that I was a little skeptical, but we tried it and it worked. The really good thing about the idea is that we're recycling, and nobody complained about how we have to get the materials to make the dam.
He's calling it The Charcoal Beer Can Band
. And he also wants everyone to know that the patent is pending!
