Devilled eggs are hard-boiled eggs that are cut in half. The yolks are mixed with binding agents such as mayonnaise and placed back into the egg white cavities. They are mostly a party food but are also wonderful for picnics, as a snack or as part of a meal when paired with veggies.
Steam eggs for 10 minutes. Cool down under cold running water. Place them in a bowl of cold water until they have cooled down completely (about 10 minutes).
