The list below is order by priority of importance, always beware the one listed at the top!
I as a microwave first-timer, I've learnt some lessons through the hard way, but I got lucky as thing didn't turn out to be disastrous.
Don't microwave egg if you are not sure! It can explodes inside your microwave
If you are cooking egg, must make sure you are not cooking the whole raw egg (no matter it's in shell or unshelled), the egg yolk inside look and feel soft, but it can explodes and shatter glasses utensil next to it.
Same as above, but it can still explode outside (if it isn't explode inside the MW)
If get lucky, the egg yolk may not explode get too hot from MW, but it's a silent before the storm. The egg yolk can still explode after you open your MW door and thing can get messy or worse, it can seriously hurt you if you stick your eye looking into the cooked egg.
Reason: after MW-ing, the vibration that generating heat inside the food won't just gone missing instantly, some of it will remain for few more seconds and still able to heat up the food, and this is what can cause "food explosion" even after you remove the egg from your MV.
NEVER MICROWAVE WITH METAL
If you try, you'll see spark when you accidentally MW with metal, even a little metal. The spark could possibly become fire and turn your MW into firecracker show in your kitchen if you microwaving metal with highest power.
Not every glass made for Microwave cooking
Yes, microwave cooking with weak glass can cause unwanted kitchen tragic. Not every glass made the same, you need to check if your utensil is "Microwave safe".
I was so stubborn at this point, until I broke a few non-microwave safe glass cups and plates.
Extra personal note: Even though some plastic-made container labeled as "microwave safe", but I still believe glass-made container/utensil is still a healthier way to prepare your meal in microwave. We can't measure how much unknown plastic material has dissolved in the food consumed in the plastic-made container.
Speaking about glass-range container, Decor product has been my all-time favorite food storage container.
Microwave is for "Heating up" food, and less suitable for "cooking"
In short, you'll need an oven if you want to really cook a tasty food. You don't cook drumstick with MW, you roast it with oven where it generate and circulate heat around to cook it.
The concept of microwave is different, it use wave to vibrate water molecules in the food rapidly to generate heat.
MW is exist to heat up your food quickly and so you can enjoy it within a few seconds to minutes.
Food become hard after microwaved
So just don't leave your food get cold again after MW cooked. As stated in the last point, once water molecule heated up and vaporised, the water is actually extracted from the food. A soft chicken would then easily turn into a piece of hard stone.
The video above is a good example of what could happen when you have not learned the concept of how microwave works (even instruction followed exactly without aberration).
In worst case, the baozi could start burning with real fire around it right inside your microwave.
