A microwave is useful for heating a dish quickly.
The problem is when you have to heat 2 plates!
You have to heat them 1 by 1. Not very practical if you eat with someone.
Especially since a dish heated in the microwave tends to cool quickly.
Discover the trick to heat 2 plates at the same time:
1. Place a plate in the microwave.
2. Then place an upside-down cup next to the plate.
3. Put the 2nd plate on top of the cup.
There you go, you can now heat 2 plates at the same time in your microwave :-)
Convenient isn't it? If you don't have a cup handy, you can also use a glass.
This trick also works to warm 2 bowls at the same time.
