Step 1: Light a fire in the Outdooroven and make sure the fire burns for at least 15 minutes before you start cooking. This way, the oven reaches the proper temperature (around 200 degrees Celsius) and the heat is distributed evenly throughout the oven. If you want to check the temperature inside the oven, you could use the Magnetic Thermometer (sold separately).
Step 2: Peel the carrots, potatoes and parsnips. Cut them into pieces of roughly the same size. Cut the onion into rings of about one and a half centimeters.
