Other methods include using a stovetop popcorn maker or an oven with a convection setting. Instead, the pop seemed to occur when water vapour inside the kernel was released, creating empty cavities inside the popcorn kernel that resonated once the pressure dropped. The popcorn convection process is a crucial part of its cooking. The main argument against using a convection setting is that it can cause the popcorn to burn.
