Re. baked potatoes and cooking times. I find that if they are less big and oval, i.e. not round then I can put an oiled skewer through them and bake them upper shelf Mk. 6 very often just for 1 hour.
Another way with potatoes - being both baked and 'roasted', is to cut them in half lengthways and criss cross the exposed flesh. Oil it and season it and bake as above, i.e. upper shelf Mk. 6. They are done in around 45 - 50 mins (depending on size) and have a lovely crispy top whilst co-starring as a baked potato underneath!
