Deviled eggs may be a staple at many American potlucks and picnics, but they have a longer history in Europe.
Variations on the stuffed eggs are common across the continent dating back to the ancient Romans, who ate hard-boiled eggs with spiced yolks. In Spain, the dish is called huevos rellenos, or stuffed eggs. Try serving the classic Spanish huevos rellenos de atún, in which the yolks are mixed with tuna, tomato sauce and mayonnaise and sprinkled with paprika.
