Call me "old fashioned" but I actually steam my corn in a large pot with a tight lid. Doesn't drip water like boiled corn does because it doesn't use a lot of water and tastes just as good. Baked potatoes? Wash them, pierce them and put them in micro "naked". If I am using my oven, I bake them along with the roast, etc. Sometimes for oven baked spuds, I will wrap them in foil, but most times I just leave them alone and bake them on the racks. You can also make baked potatoes and corn on the BBQ grill, just don't put them over the flame or hot side. Leave husks on corn and either wrap potatoes in foil or not. Place over indirect heat (cooler side of grill). Just writing about corn and spuds is making me hungry!
Glad to hear you were not injured and your micro was not damaged.
