Mix the egg with a small part of the milk. Put the cream, remaining milk and sugar in a saucepan and bring to the boil.
Chop up the toffifees with a mixer, add them to the hot milk and let dissolve while stirring. Stir the alcohol into the boiling mixture, remove the saucepan from the heat immediately, stir in the egg-milk mixture quickly and pour it through a sieve into a separate measuring beaker to remove the nuts from the toffifees.
Then fill the finished liqueur into suitable vessels and let it cool down.
Can e.g., Coffee or hot chocolate are added, tastes very good!
