Place the eggs in a saucepan. Cover with cold water and bring to a boil. Once the water has come to a boil reduce the heat and simmer for 15 minutes.
Remove from the water once the eggs are cool enough to handle gently roll them on a hard surface to crack the eggshell without removing the shell.
Place into a bowl with water and black food colouring for at least 30 minutes.
Remove the eggs from the bowl, gently remove the shell and rinse the eggs.
Halve the eggs removing the yolk and placing into a separate bowl. Set aside the white part of the egg to fill later.
In the bowl combine the egg yolks, mayo, guacamole, hot sauce, salt, and pepper until smooth. Fill the egg white shells using a piping bag. Garnish with chives.
