This episode, we're taking you on a whirlwind tour through oven history and science, from the legendary roast beef of Old England—and the special dogs bred to turn the spits on which it hung—to the curious origins of the microwave in military radar technology. This episode, we travel with food writer Bee Wilson and historian Sara Pennell to 1600s England, to tell the story of one culture's challenging transition from hearth to enclosed oven—a story that starts with a wood famine, involves the demise of a specialist breed of dog and a nostalgic song about the lost art of roasting, and ends up effecting a radical redesign of both the art of cooking and our relationship with fire.
