So, some pictures...
The first is the setup. It's made from an old lorry tire rim (if that's the correct word). The baking plate is also made from the same material.
Ok, put some oil in and then the batter (the brown rim on the batter is the oil). put the cheese on and the (slightly pre-fried) bacon. Wait a bit and pour a second (much thinner layer of batter on top of that. Turn it around, wait a minute or so and put it on your plate.
Result on the third picture! Yummie!
(naturally, if you actually bake in a baking pan, you'll get much rounder results
)
