The special thing about this unusual cooking competition: In each episode, the two top chefs decide in which country the other chef must complete his difficult task. After arriving in the respective country, the two competitors are served the favorite dish of his regular guests by a local chef in the black "Kitchen Impossible" box. They then have to prepare the dish they tasted in the kitchen themselves to the best of their knowledge and ability, copying it as precisely as possible. The highlight: In "Kitchen Impossible" both the exact recipe and the list of ingredients remain a secret for the two chefs.
