I'm posting for traffic really - of course I know HOW to cook a jacket potato.....!
But tonight I will need to be out the house for over 2 hours and I need them to be ready when we all get in (parents evening!)
I only have my oven - please don't say microwave [bleugh!!!!!] What temperature do you think I could put them on in the oven and go out for a couple of hours and them be ready when I get home but not totally burned to a crisp?
