How do you hard-cook eggs so the yolk is centered when the eggs are cut in half? —J.N., Mead, Nebraska
As an egg ages, the yolk moves more freely and can become displaced as the white thins out. Using fresh eggs will reduce the chance of having off-centered yolks. Unfortunately, fresh hard-cooked eggs are hard to peel. To have centered yolks in eggs that are still easy to peel, use eggs that have been refrigerated for a week to 10 days. Researchers have also found that eggs stored on their sides have the most consistently centered yolks. Secure the carton of eggs closed with a rubber band, and turn it on its side in the refrigerator up to 24 hours before cooking.
