Does anyone have any idea what this pan is called? It has a bottom dish and a rack that sits on top with several “legs”. It has a cover. There is a hole in the center of both the bottom part and the rack. I'm told it's from Argentina. I'm not sure how to use it and I can’t find anything online.
It looks like a "smokeless" stove top grill very similar to the one my mother used to have. Unfortunately I can't find any pictures online but the setup is the same.
You put it on a burner and add water to the lower plate. Food goes on the perforated plate, and you put the cover on to prevent heat from escaping. Fat drips onto the bottom plate with water, so it doesn't burn and doesn't create smoke.
I don't believe it's a Korean grill plate; in those usually the center is closed, both for creating a hot spot and to prevent grease from falling on top of the burner. In the one from the question the food doesn't go directly on top of the burner, it cooks like in an oven not with direct heat.
