Microwaves are convenient for reheating and cooking food. However, in some cases, the microwave oven heats up the entire container such as a plate or tupperware, making it impossible to remove it directly by hand. If you touch it forcibly, you may get burned or spill the contents...
A convenient item that can prevent such tragedies is the "Big Microwave Tray" from the 100 yen store Daiso. It is a special tray that does not get hot even when heated in the microwave.
Daiso "Microwave Tray Big"
It's easy to use. Place a plate or tupperware with food on the tray and place it in the microwave oven. Just heat it as usual and you're good to go. Please note that this tray cannot be used in the oven. Do not place food directly on the tray.
After heating, the plate with the food is hot. But the tray is not hot!
You can use it as a tray as it is, or you can slide it out to transfer plates to the table, which will reduce the time you need to touch it.
You can use it as a tray until the plate is heated up.
It is especially useful for reheating cooked vegetables and soups and stews that have a lot of water in them. The size is rather large (29 x 29), so please check the size of your microwave oven before purchasing.
