At first thought I use the Nuke for only reheat and defrosting.
I don't remember the last time I actually baked a potato. And I've taken to pre-cooking potatoes I'm going to fry, it greatly cuts down on the pan time.
Use to do allot of popcorn in the Nuke.
I use the Nuke for warming fluids used in bread making. Advantage is the 'bowl' warms with the fluid so I don't have to overheat the fluid(s) on the range to compensate for warming the 'yeast proofing' bowl, or the large glass measuring 'cup' for disolving 'sugars', and so on.
Defrosting is a bit tricky. Follow the microwave directions and you'll more than likely par cook the food. Our present unit has a auto-defrost based on weight. If I set the machine for the items actual weight its coming out of there cooked. I set the Nuke for 1/3 to 1/2 the items weight for the first cycle and check. Then I may run again at the same or lesser weight, or cover with a towel at room temp, or put it in the fridge, or, or,, whatever.
Trick is you have to let the heat of the hot spots drift into the cold spots.
Now excuse me, I have to heat up some coffee.
