Not sure if this is the correct place to post this but here goes. My wife has a very simple popover recipe. They get baked in a popover pan and usually come out very high with the right amount of crispiness outside and fluffiness inside. Earlier this year, we moved from CT to SC and went from an electric stove to natural gas. She has yet to get her popovers to come out they way they did when using electric. What could possibly be the problem?
