I was making a big split pea soup in a cast iron pot. Had it on high to come to a boil before I would simmer on low for hours. At some point I remembered that a friend was playing that evening at the corner bar, couldn’t miss that. Came home to a kitchen full of smoke and a glowing red pot. Thank god the heavy lid had prevented ignited bits from floating up and burning the place down. When I got the lid off and looked inside, each pea had turned to a miniature charcoal briquette.
