Meanwhile, in 10-inch skillet, heat 2 to 3 inches water to boiling; reduce heat so water is simmering. Break cold egg into custard cup or small glass bowl. Holding cup close to water’s surface, carefully slide egg into water. Repeat with 3 more eggs. Cook uncovered 3 to 5 minutes or until whites and yolks are firm, not runny. Remove eggs with slotted spoon; cover with foil to keep warm. Repeat with remaining 4 eggs.
