What is the meaning of pop over pan?

A popover pan is a pan that is specially designed for making popovers, which are a type of light, hollow roll made from a batter of flour, milk, and eggs. Popover pans have deep wells that allow the popovers to rise tall and crispy, and they have a non-stick coating that makes it easy to remove the popovers from the pan. Popover pans come in a variety of sizes, and they can be made from different materials, such as metal, silicone, or ceramic.
