For perfect hard-cooked eggs, put eggs in a large saucepan with cold water to cover them by 1-inch. Cover and bring to a boil over high heat. Remove from heat and let stand covered 15 minutes. Pour off water; put pan under running water to stop further cooking. When cool enough to handle, crack shells and peel. To prevent the black ring around the edge of the egg, plunge straight into cold water after cooking.

Perfect Hard-Boiled Eggs
Place eggs in saucepan with water to cover as usual. When water comes to a boil remove from heat and let set 20 minutes covered. The eggs will finish cooking, yolks perfectly centered and no green every time. Sherri from Fort Worth, Texas
