Feeling devilish? Add spooky fun to your holiday party with this colorfully creepy version of a classic appetizer that looks ghoulish but tastes heavenly!
In a deep bowl, mix together the water and blue food coloring.
Use your hands and the back of a spoon to crackle the shells of the hard-boiled eggs. You can also gently push while rolling the eggs on a countertop to get the shells nicely crackled.
Add the crackled eggs to the colored water and place in the fridge for 2 hours. If the eggs aren’t completely submerged, turn them over halfway through so that all sides have some time being fully submerged in the colored water.
Take the eggs out of the colored water, dry them off, and then carefully peel off the shells.
Gently slice the eggs in half and scoop out the yolks. Add the yolks to a food processor with the mayonnaise, mustard, green food coloring, salt, and pepper. Blend until smooth.
Scoop the green egg-yolk mixture into a piping bag. Pipe the mixture into the hollow egg white halves.
