Cast Iron Cookware hasn't changed much since the turn of the century. That's about to change as Jason and John, owners of Borough Furnace, bring cast iron cookware into the 21st century. John and Jason have launched a Kickstarter campaign to raise funds to build a modern day foundry to create cast iron cookware and more, and I talked to them by phone for GardenFork Radio.

Thanks to The Kitchn and Monica for telling us about these guys.
