What is that pop on the stove?

The pop you hear on the stove is often caused by moisture in food or oil reaching high temperatures and rapidly turning into steam. This steam can create pressure that causes small bursts or pops as it escapes. Additionally, if you're cooking something like bacon or frying, the water content in the food can lead to similar popping sounds. It's a normal part of cooking, but you should always be cautious to avoid splatters.
