Q: Is it better to bake a russet potato using convection bake or regular bake? And what temperature do you recommend for either? I have a home oven (GE profile) that has both regular bake and convection bake settings; the convection is "True European Convection with Direct Air; it combines a top and bottom bake element with a third loop in the back." We spear the potatoes lengthwise with a metal skewer to conduct heat to the interior.
