Sugar decoration and chocolate rolls to decorate.
Heat cream in a pot (do not boil!). Break the chocolate into pieces and melt in the cream while stirring. Pour into a mixing bowl and let it cool down. Chill for at least 4 hours.
Cut the orange in half and squeeze. Unroll the surprise eggs and carefully halve them. Coarsely chop the Amarettini, up to 8 pieces, and distribute in the egg halves. Drizzle with orange juice.
Whip the chocolate cream with the whisk of the hand mixer until stiff.
Pour cream into a piping bag with a large star-shaped spout. Pour into the egg halves. Decorate with remaining amarettini, sugar decoration and chocolate rolls.
