I'm doing stuffed baked potatoes for dinner tonight, so need them to have a 'crispy' edge - ie Oven Baked rather than how I usually do them in the Microwave - however I've left it a bit late to cook them completely in the oven, is it possible to cook start them off in the Microwave and then harden the skins up in the oven? If so how long should I microwave them for, and how long will they need in the oven??
