I guess I'm the microwave queen!
We have 10 microwaves in our kitchen. (of course it's a restaurant)...and we use all of them constantly.
They are wonderful so many things that I don't have the time to "stand over the stove for".
However, that being said...there's many things I would never cook in a microwave also.
But here's how we use ours.
20 Different candies.
All our cream pie fillings.
Precooking all our fruit pie fillings before putting into crust.
Many sauces...sweet and sour...cherry sauce...white sauce.
Bakers that we precook...for many things like potato salad...au gratin potatoes...potato plates.
We precook our pastas on the stove...refrigerate...then at serving put them on a plate....warm the sauces in the microwave...put over the pastas...and heat.
I have cooked hamburger in the microwave....(works great if you stir it enough). We cook all our meatloafs...stuffed peppers...cabbage rolls...in it.
And of course for reheating...all the chili's...spaghetti sauces etc...that are preportioned.
I bake all our bread...immediately freeze...then re-warm each day.
So though I wouldn't exactly say we "cook" in it. We use them all daily for a number of purposes....and I'd be lost without them!
I think for many who do not use them much...maybe it's just that you're not quite sure how to? Or maybe you aren't aware that they are so easy to use for things that you normally have to stand over a stove and stir. Just takes a little practice...and "want to" usually.
There's not a darn thing wrong with the "stove" method if you prefer it though!
