The common recommendation is to not microwave prepackaged popcorn directly on a plate. Instead, microwave it in its original bag. However, if you're popping kernels from scratch, using a microwave-safe plate beneath a microwave-safe bowl is the recommended method. This answer assumes you're asking about prepackaged microwave popcorn.
Here's why and what to consider:
-
Heat Stress: Directly microwaving prepackaged popcorn on a glass plate can cause it to overheat, potentially leading to cracking or breaking. The bag is designed to distribute heat more effectively.
-
Cleanliness: Popping popcorn in its bag minimizes the risk of oily residue accumulating on your plate.
Therefore, if you are using prepackaged popcorn, it's best to follow the instructions on the bag and microwave it in the bag itself. If you're using kernels and a microwave-safe bowl, then using a plate beneath that is the recommended way to microwave them.
