A cooking show where every episode, the chef gets possessed by the ghost of a random person of another era, who then proceeds to cook something that they personally enjoyed as a meal while they were alive.
It remains unclear how, regardless from the historical time and place, every single "guest star" seems to have a full understanding of what a cooking show is, and also how to operate a modern kitchen. While there is no overarching plot, different context clues heavily imply that the host chef is somehow a very easy person to possess, and there are so, so many souls from all eras of human history who would love to hop in to experience the pleasure of getting to cook one more really nice meal.
