Method
1. Pre-heat the oven to 200ºC.
2. Melt the butter without browning.
3. Brush a large black pan with melted butter.
4. Place a layer off sliced potatoes on the bottom of the pan & season lightly.
5. Build up layers of the onions, carrots, potatoes & rosemary seasoning as you go & drizzling with butter until the pan is stacked full.
6. Take into account that the potato will fall as it cooks so the finished item will be a lot flatter than before it went into the oven.
7. While in the oven press down the potato at regular intervals to ensure a good finish.
8. It is cooked when a sharp knife slides through easily.
