When it comes to transporting a party tray of deviled eggs, the slippery round bottoms of the eggs can make them fall over and squish together if you're using a flat plate.
To safely transport your deviled eggs, wash a plastic egg carton with soap and hot water, rinse it, and let it dry completely before individually adding the eggs.
Use the "prongs" of the carton to hold up the egg at the corners, close the carton carefully, and refrigerate it until it's time to transport.
If the container has no lid, carefully cover it with a foil tent. For foam or cardboard egg cartons, line the bottom with aluminum foil or plastic wrap to avoid contamination.
