Some folks at the Dolphin Bay Hotel, which is on a Hawaiian island right next to Mt. Kilauea, have come up with a
unique new way to cook... with molten lava. Here they have taken a bit of 2000-degree F rock, and have placed a game hen wrapped in leaves on it...
...and covered it all with a second piece of 2000-degree lava.
After 45 minutes the lava has dropped to 450 and has hardened; they bust it open with a shovel and eat the cooked meat inside.
I believe that it works and all, but I would rather not have to wash volcanic dust off my entree.
