Cut on the top a small piece of egg that will be used as the “hat” part.
Take the egg yolk out from the 4 eggs and mix it with some moustard and Mayonnaise ! (forgot it on he pic).
Then put the mixture back into the eggs and try to give them some shape.
Add the “hats” and use an black olive to cut out tiny eyes and a carrot for the beaks.
Admire for a while and enjoy, it’s yummy !
