Put the eggs in boiling water and boil hard for about 10 minutes. Drain, rinse with cold water and remove the shell. Let them cool down. Cut a lid off the eggs. Carefully remove the egg yolk with a knife or teaspoon.
Pass the egg yolk through a sieve into a bowl. Mix with mustard, honey and crème fraîche. Wash the dill, dab dry, put something aside for garnishing. Cut the rest very finely. Stir into the egg cream, season with salt.
Pour into a piping bag with star-shaped spout and squirt into the eggs. Wash the crabs and drain them well. Garnish eggs with dill and crabs.
