How to roast stuff - an idiots' guide by an idiot :)
by inspirewithhope
1. Wash
2. Slice up - similar sizes is a good idea to ensure it cooks at the same time
3. Stick in oven on fairly high heat (two-thirds of the dial hot :) so Gas Mark 6 or 7)
4. Leave in oven
5. Occasionally look at
6. Remove when brown on outside & soft on inside (poke with a fork to check)
Remember…
Use oven gloves
Some things take a lot longer than other things - root vegetables like carrots, potatoes etc take ages. (Although I like my carrots crunchy). Potatoes might need, say, half an hour whilst mushrooms might need 10 minutes. Experiment. Keep looking & smelling.
Good luck!
