I have my own, my mother’s, and my grandmother’s cast iron, plus a few miscellaneous pieces rescued from the Boy Scouts and Goodwill. Every year after we deep fry the Thanksgiving turkey, we put all the cast iron in the leftover hot oil to season overnight. I’d love the directions to the Dutch oven cobbler.
Bam!

You can substitute canned blueberries for the peaches.
