Deviled eggs, also known as stuffed eggs, curried eggs or dressed eggs, are hard-boiled eggs that have been peeled, cut in half, and filled with the yolk, mixed with other ingredients such as mayonnaise and mustard. They are generally served cold as a side dish, appetizer or a main course during gatherings or parties. The dish's origin can be seen in recipes for boiled, seasoned eggs as far back as ancient Rome, where they were traditionally served as a first course. The dish is popular in Europe, North America and Australia.

Boiled eggs are eggs, typically from a chicken, cooked with their shells unbroken, usually by immersion in boiling water. Hard-boiled eggs are cooked so that the egg white and egg yolk both solidify, while soft-boiled eggs may leave the yolk, and sometimes the white, at least partially liquid and raw. Boiled eggs are a popular breakfast food around the world.
