I should have expected that this was a thing.
As a youngish adult was thoroughly with my father improvising something like this to cook a turkey. For complicated reasons, my parents volunteered to bring the turkey to a family Thanksgiving three hours’ drive away. My dad’s not much interested in cooking, but looked at the project as a physics problem. He concluded that, if you got enough heat into the outer bits and then put it in a sufficiently insulated box, the temperature would equilibrate during the drive. It was actually one of the better cooked turkeys I’ve eaten.
