Fill a medium bowl with iced water; set aside. Fill a large wide saucepan with about 4 inches of water; bring to a boil. Reduce heat to medium, so water is barely simmering. Break 1 egg at a time into a small heatproof bowl. Gently tip bowl into water, letting egg slide into the water. Using a spoon, cover yolk with some of the egg white; repeat with remaining 3 eggs. When eggs begin to become opaque, carefully transfer eggs using a slotted spoon to iced water to stop cooking. Trim edges with a small knife or scissors to create a uniform shape.
